Final Handshake
---------------
After the protocol has been shut down, the final handshake is
performed. This handshake has no real purpose, and some UUCP packages
simply drop the connection rather than do it (in fact, some will drop
the connection immediately after both sides agree to hangup, without
even closing down the protocol). Taylor UUCP always sends the
appropriate final handshake string (in `fdo_call' or `faccept_call')
but ignores the handshake string from the other side unless it is in
`handshake' debugging mode.
caller: `\020OOOOOO\000'
called: `\020OOOOOOO\000'
That is, the calling UUCP sends six letter O's and the called UUCP
replies with seven letter O's. Some UUCP packages always send six O's.

The UUCP `g' Protocol
=====================
The `g' protocol is a packet based flow controlled error correcting
protocol that requires an eight bit clear connection. It is the
original UUCP protocol, and is supported by all UUCP implementations.
Many implementations of it are only able to support small window and
packet sizes, specifically a window size of 3 and a packet size of 64
bytes, but the protocol itself can support up to a window size of 7 and
a packet size of 4096 bytes. Complaints about the inefficiency of the
`g' protocol generally refer to specific implementations, rather than
the correctly implemented protocol.
The `g' protocol was originally designed for general packet drivers,
and thus contains some features that are not used by UUCP, including
an alternate data channel and the ability to renegotiate packet and
window sizes during the communication session.
The `g' protocol is spoofed by many Telebit modems. When spoofing
is in effect, each Telebit modem uses the `g' protocol to communicate
with the attached computer, but the data between the modems is sent
using a Telebit proprietary error correcting protocol. This allows
for very high throughput over the Telebit connection, which, because
it is half-duplex, would not normally be able to handle the `g'
protocol very well at all.
This discussion of the `g' protocol explains how it works, but does
not discuss useful error handling techniques. Some discussion of this
can be found in Jamie E. Hanrahan's paper (*note Documentation
references::.). A detailed examination of the source code would also
be profitable.
The Taylor UUCP code to handle the `g' protocol is in the file
`protg.c'. There are a number of functions; the most important ones
are `fgstart', `fgsend_control', `fgsenddata', and `fgprocess_data'.
All `g' protocol communication is done with packets. Each packet
begins with a six byte header. Control packets consist only of the
header. Data packets contain additional data.
The header is as follows:
`\020'
Every packet begins with a `^P'.
K (1 <= K <= 9)
The K value is always 9 for a control packet. For a data packet,
the K value indicates how must data follows the six byte header.
The amount of data is 2 ** (K + 4), where ** indicates
exponentiation. Thus a K value of 1 means 32 data bytes and a K
value of 8 means 4096 data bytes. The K value for a data packet
must be between 1 and 8 inclusive.
checksum low byte
checksum high byte
The checksum value is described below.
control byte
The control packet indicates the type of packet, and is described
below.
xor byte
This byte is the xor of K, the checksum low byte, the checksum
high byte and the control byte (i.e. the second, third, fourth
and fifth header bytes). It is used to ensure that the header
data is valid.
The control byte in the header is composed of three bit fields,
referred to here as TT (two bits), XXX (three bits) and YYY (three
bits). The complete byte is TTXXXYYY, or (TT << 6) + (XXX << 3) + YYY.
The TT field takes on the following values:
0
This is a control packet. In this case the K byte in the header
must be 9. The XXX field indicates the type of control packet;
the types are described below.
1
This is an alternate data channel packet. This is not used by
UUCP.
2
This is a data packet, and the entire contents of the attached
data field (whose length is given by the K byte in the header) are
valid. The XXX and YYY fields are described below.
3
This is a short data packet. Let the length of the data field
(as given by the K byte in the header) be `l'. Let the first
byte in the data field be `b1'. If `b1' is less than 128 (if the
most significant bit of `b1' is 0), then there are `l - b1' valid
bytes of data in the data field, beginning with the second byte.
If `b1 >= 128', let `b2' be the second byte in the data field.
Then there are `l - ((b1 & 0x7f) + (b2 << 7))' valid bytes of data
in the data field, beginning with the third byte. In all cases
`l' bytes of data are sent (and all data bytes participate in the
checksum calculation) but some of the trailing bytes may be
dropped by the receiver. The XXX and YYY fields are described
below.
In a data packet (short or not) the XXX field gives the sequence
number of the packet. Thus sequence numbers can range from 0 to 7,
inclusive. The YYY field gives the sequence number of the last
correctly received packet.
Each communication direction uses a window which indicates how many
unacknowledged packets may be transmitted before waiting for an
acknowledgement. The window may range from 1 to 7 packets, and may be
different in each direction. For example, if the window is 3 and the
last packet acknowledged was packet number 6, packet numbers 7, 0 and 1
may be sent but the sender must wait for an acknowledgement before
sending packet number 2. This acknowledgement could come as the YYY
field of a data packet or as the YYY field of a `RJ' or `RR' control
packet (described below).
Each packet must be transmitted in order (the sender may not skip
sequence numbers). Each packet must be acknowledged, and each packet
must be acknowledged in order.
In a control packet, the XXX field takes on the following values:
1 `CLOSE'
The connection should be closed immediately. This is typically
sent when one side has seen too many errors and wants to give up.
It is also sent when shutting down the protocol. If an
unexpected `CLOSE' packet is received, a `CLOSE' packet should be
sent in reply and the `g' protocol should halt, causing UUCP to
enter the final handshake.
2 `RJ' or `NAK'
The last packet was not received correctly. The YYY field
contains the sequence number of the last correctly received
packet.
3 `SRJ'
Selective reject. The YYY field contains the sequence number of a
packet that was not received correctly, and should be
retransmitted. This is not used by UUCP, and most
implementations will not recognize it. Taylor UUCP will
recognize it but not generate it.
4 `RR' or `ACK'
Packet acknowledgement. The YYY field contains the sequence
number of the last correctly received packet.
5 `INITC'
Third initialization packet. The YYY field contains the maximum
window size to use.
6 `INITB'
Second initialization packet. The YYY field contains the packet
size to use. It requests a size of 2 ** (YYY + 5). Note that
this is not the same coding used for the K byte in the packet
header (it is 1 less). Some UUCP implementations can handle any
packet size up to that specified; some can only handled exactly
the size specified. Taylor UUCP will always accept any packet
size.
7 `INITA'
First initialization packet. The YYY field contains the maximum
window size to use.
To compute the checksum, call the control byte (the fifth byte in
the header) `c'.
The checksum of a control packet is simply `0xaaaa - c'.
The checksum of a data packet is `0xaaaa - (CHECK ^ c)' (`^'
denotes exclusive or, as in C), and `CHECK' is the result of the
following routine run on the contents of the data field (every byte in
the data field participates in the checksum, even for a short data
packet). Below is the routine used by Taylor UUCP; it is a slightly
modified version of a routine which John Gilmore patched from G.L.
Chesson's original paper. The `z' argument points to the data and the
`c' argument indicates how much data there is.
int
igchecksum (z, c)
register const char *z;
register int c;
{
register unsigned int ichk1, ichk2;
ichk1 = 0xffff;
ichk2 = 0;
do
{
register unsigned int b;
/* Rotate ichk1 left. */
if ((ichk1 & 0x8000) == 0)
ichk1 <<= 1;
else
{
ichk1 <<= 1;
++ichk1;
}
/* Add the next character to ichk1. */
b = *z++ & 0xff;
ichk1 += b;
/* Add ichk1 xor the character position in the buffer
counting from the back to ichk2. */
ichk2 += ichk1 ^ c;
/* If the character was zero, or adding it to ichk1
caused an overflow, xor ichk2 to ichk1. */
if (b == 0 || (ichk1 & 0xffff) < b)
ichk1 ^= ichk2;
}
while (--c > 0);
return ichk1 & 0xffff;
}
When the `g' protocol is started, the calling UUCP sends an INITA
control packet with the window size it wishes the called UUCP to use.
The called UUCP responds with an INITA packet with the window size it
wishes the calling UUCP to use. Pairs of INITB and INITC packets are
then similarly exchanged. When these exchanges are completed, the
protocol is considered to have been started. The window size is sent
twice, with both the INITA and the INITC packets.
When a UUCP package transmits a command, it sends one or more data
packets. All the data packets will normally be complete, although some
UUCP packages may send the last one as a short packet. The command
string is sent with a trailing null byte, to let the receiving package
know when the command is finished. Some UUCP packages require the last
byte of the last packet sent to be null, even if the command ends
earlier in the packet. Some packages may require all the trailing
bytes in the last packet to be null, but I have not confirmed this.
When a UUCP package sends a file, it will send a sequence of data
packets. The end of the file is signalled by a short data packet
containing zero valid bytes (it will normally be preceeded by a short
data packet containing the last few bytes in the file).
Note that the sequence numbers cover the entire communication
session, including both command and file data.
When the protocol is shut down, each UUCP package sends a `CLOSE'
control packet.

File: uucp.info, Node: f Protocol, Next: t Protocol, Prev: g Protocol, Up: Protocols
The UUCP `f' Protocol
=====================
The `f' protocol is a seven bit protocol which checksums an entire
file at a time. It only uses the characters between \040 and \176
(ASCII space and `~') inclusive as well as the carriage return
character. It can be very efficient for transferring text only data,
but it is very inefficient at transferring eight bit data (such as
compressed news). It is not flow controlled, and the checksum is
fairly insecure over large files, so using it over a serial connection
requires handshaking (`XON'/`XOFF' can be used) and error correcting
modems. Some people think it should not be used even under those
circumstances.
I believe the `f' protocol originated in BSD versions of UUCP. It
was originally intended for transmission over X.25 PAD links.
The Taylor UUCP code for the `f' protocol is in `protf.c'.
The `f' protocol has no startup or finish protocol. However, both
sides typically sleep for a couple of seconds before starting up,
because they switch the terminal into `XON'/`XOFF' mode and want to
allow the changes to settle before beginning transmission.
When a UUCP package transmits a command, it simply sends a string
terminated by a carriage return.
When a UUCP package transmits a file, each byte b of the file is
translated according to the following table:
0 <= b <= 037: 0172, b + 0100 (0100 to 0137)
040 <= b <= 0171: b ( 040 to 0171)
0172 <= b <= 0177: 0173, b - 0100 ( 072 to 077)
0200 <= b <= 0237: 0174, b - 0100 (0100 to 0137)
0240 <= b <= 0371: 0175, b - 0200 ( 040 to 0171)
0372 <= b <= 0377: 0176, b - 0300 ( 072 to 077)
That is, a byte between \040 and \171 inclusive is transmitted as
is, and all other bytes are prefixed and modified as shown.
When all the file data is sent, a seven byte sequence is sent: two
bytes of \176 followed by four ASCII bytes of the checksum as printed
in base 16 followed by a carriage return. For example, if the
checksum was 0x1234, this would be sent: "\176\1761234\r".
The checksum is initialized to 0xffff. For each byte that is sent
it is modified as follows (where `b' is the byte before it has been
transformed as described above):
/* Rotate the checksum left. */
if ((ichk & 0x8000) == 0)
ichk <<= 1;
else
{
ichk <<= 1;
++ichk;
}
/* Add the next byte into the checksum. */
ichk += b;
When the receiving UUCP sees the checksum, it compares it against
its own calculated checksum and replies with a single character
followed by a carriage return.
`G'
The file was received correctly.
`R'
The checksum did not match, and the file should be resent from the
beginning.
`Q'
The checksum did not match, but too many retries have occurred
and the communication session should be abandoned.
The sending UUCP checks the returned character and acts accordingly.

File: uucp.info, Node: t Protocol, Next: e Protocol, Prev: f Protocol, Up: Protocols
The UUCP `t' Protocol
=====================
The `t' protocol is intended for TCP links. It does no error
checking or flow control, and requires an eight bit clear channel.
I believe the `t' protocol originated in BSD versions of UUCP.
The Taylor UUCP code for the `t' protocol is in `prott.c'.
When a UUCP package transmits a command, it first gets the length
of the command string, C. It then sends ((C / 512) + 1) * 512 bytes
(the smallest multiple of 512 which can hold C bytes plus a null byte)
consisting of the command string itself followed by trailing null
bytes.
When a UUCP package sends a file, it sends it in blocks. Each block
contains at most 1024 bytes of data. Each block consists of four bytes
containing the amount of data in binary (most significant byte first,
the same format as used by the Unix function `htonl') followed by that
amount of data. The end of the file is signalled by a block
containing zero bytes of data.

File: uucp.info, Node: e Protocol, Next: x Protocol, Prev: t Protocol, Up: Protocols
The UUCP `e' Protocol
=====================
The `e' protocol is similar to the `t' protocol. It does no flow
control or error checking and is intended for use over TCP.
The `e' protocol originated in versions of BNU UUCP.
The Taylor UUCP code for the `e' protocol is in `prote.c'.
When a UUCP package transmits a command, it simply sends the
command as an ASCII string terminated by a null byte.
When a UUCP package transmits a file, it sends the complete size of
the file as an ASCII decimal number. The ASCII string is padded out
to 20 bytes with null bytes (i.e., if the file is 1000 bytes long, it
sends `1000\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0'). It then sends the
entire file.

File: uucp.info, Node: x Protocol, Next: d Protocol, Prev: e Protocol, Up: Protocols
The UUCP `x' Protocol
=====================
I believe that the `x' protocol was intended for use over X.25
virtual circuits. It relies on a write of zero bytes being read as
zero bytes without stopping communication. I have heard that it does
not work correctly. If someone would care to fill this in more, I
would be grateful. Taylor UUCP does not implement the `x' protocol.

File: uucp.info, Node: d Protocol, Next: Capital G Protocol, Prev: x Protocol, Up: Protocols
The UUCP `d' Protocol
=====================
This is apparently used for DataKit connections, and relies on a
write of zero bytes being read as zero bytes, much as the `x' protocol
does. I don't really know anything else about it. Taylor UUCP does
not implement the `d' protocol.

File: uucp.info, Node: Capital G Protocol, Next: Documentation References, Prev: d Protocol, Up: Protocols
The UUCP `G' Protocol
=====================
The `G' protocol is apparently simply the `g' protocol, except that
it is known to support all possible window and packet sizes. It was
introduced by SVR4 UUCP; the SVR4 implementation of the `g' protocol
is apparently fixed at a packet size of 64 and a window size of 7.
Taylor UUCP does not recognize the `G' protocol. It does support all
window and packet sizes for the `g' protocol.

File: uucp.info, Node: Documentation References, Prev: Capital G Protocol, Up: Protocols
Documentation References
========================
I took a lot of the information from Jamie E. Hanrahan's paper in
the Fall 1990 DECUS Symposium, and from Managing UUCP and Usenet by Tim
O'Reilly and Grace Todino (with contributions by several other people).
The latter includes most of the former, and is published by O'Reilly &
Associates, Inc.
Some information is originally due to a Usenet article by Chuck
Wegrzyn. The information on the `g' protocol comes partially from a
paper by G.L. Chesson of Bell Laboratories, partially from Jamie E.
Hanrahan's paper, and partially from source code by John Gilmore. The
information on the `f' protocol comes from the source code by Piet
Berteema. The information on the `t' protocol comes from the source
code by Rick Adams. The information on the `e' protocol comes from a
Usenet article by Matthias Urlichs.

source code itself.

File: uucp.info, Node: System Dependence, Next: Naming Conventions, Prev: Hacking, Up: Hacking
System Dependence
=================
The code is carefully segregated into a system independent portion
and a system dependent portion. The system dependent code is in
`sys?.*' and `tcp.c'. Note that `sysh.*' is included as `sysdep.h'.
Currently the only system dependent files are for Unix, and the file
name for all of them ends in `.unx'. Hopefully the code will
eventually be ported to other systems.
With the right configuration parameters, the system independent code
calls only ANSI C functions. Some of the less common ANSI C functions
are also provided in `util.c'. The replacement function `strtol' in
`util.c' assumes that the characters `A' to `F' and `a' to `f' appear
in strictly sequential order. The function `igradecmp' in `config.c'
assumes that the upper and lower case letters appear in order. Both
assumptions are true for ASCII and EBCDIC, but neither is guaranteed
by ANSI C. The replacement function `memmove' in `util.c' assumes
that two arbitrary pointers may be safely compared. Disregarding
these caveats, I believe that the system independent portion of the
code is strictly conforming.
That's not too exciting, since all the work is done in the system
dependent code. I think that this code can conform to POSIX 1003.1,
given the right compilation parameters. I'm a bit less certain about
this, though.
The code is in use on a 16 bit segmented system with no function
prototypes, so I'm certain that all casts to long and pointers are done
when necessary.
The code uses alloca extensively. It comes with a simple
replacement, in `alloca.c' (otherwise I would lost ANSI C conformance,
after all). Using a real `alloca' function will be considerably more
efficient. It will also cause significant stack usage, which may be a
problem on systems without virtual memory.

File: uucp.info, Node: Naming Conventions, Next: Patches, Prev: System Dependence, Up: Hacking
Naming Conventions
==================
I use a modified Hungarian naming convention for my variables and
functions. As with all naming conventions, the code is rather opaque
if you are not familiar with it, but becomes clear and easy to use with
time.
The first character indicates the type of the variable (or function
return value). Sometimes additional characters are used. I use the
following type prefixes:
`a'
array; the next character is the type of an element
`b'
byte or character
`c'
count of something
`e'
stdio FILE *
`f'
boolean
`i'
generic integer
`l'
double
`o'
file descriptor (as returned by open, creat, etc.)
`p'
generic pointer
`q'
pointer to structure
`s'
structure
`u'
void (function return values only)
`z'
character string
A generic pointer ('p') is sometimes a `void *', sometimes a
function pointer in which case the prefix is pf, and sometimes a
pointer to another type, in which case the next character is the type
to which it points (pf is overloaded).
An array of strings (`char *[]') would be named `az' (array of
string). If this array were passed to a function, the function
parameter would be named `paz' (pointer to array of string).
Note that the variable name prefixes do not necessarily indicate the
type of the variable. For example, a variable prefixed with i may be
int, long or short. Similarly, a variable prefixed with b may be a
char or an int; for example, the return value of getchar would be
caught in an int variable prefixed with b.
For a non-local variable (extern or file static), the first
character after the type prefix is capitalized.
Most static variables and functions use another letter after the
type prefix to indicate which module they come from. This is to help
distinguish different names in the debugger. For example, all static
functions in `protg.c', the `g' protocol source code, use a module
prefix of `g'. This isn't too useful, as a number of modules use a
module prefix of `s'.

Patches
=======
I am always grateful for any patches sent in. Much of the
flexibility and portability of the code is due to other people.
Please do not hesitate to send me any changes you have found necessary
or useful.
I rarely apply the patches directly. Instead I work my way through
them and apply each one separately. This ensures that the naming
remains consistent and that I understand all the code.

****************
This is a list of people who gave help or suggestions while I was
working on the Taylor UUCP project. Appearance on this list does not
constitute endorsement of the program, particularly since some of the
comments were criticisms. I've probably left some people off, and I
apologize for any oversight; it does not mean your contribution was
unappreciated.
First of all, I would like to thank the people at Infinity
Development Systems (formerly AIRS, which lives on in the domain name,
at least for now) for permitting me to use their computers and `uunet'
access. I would also like to thank Richard Stallman
`<rms@gnu.ai.mit.edu>' for founding the Free Software Foundation and
John Gilmore `<gnu@cygnus.com>' for writing the initial version of
gnuucp which was a direct inspiration for this somewhat larger
project. Chip Salzenberg `<chip@tct.com>' contributed many early
patches. Franc,ois Pinard `<pinard@iro.umontreal.ca>' tirelessly
tested the code and suggested many improvements. He also put together
the initial version of this document. Finally, Verbus M. Counts
`<verbus@westmark.com>' and Centel Federal Systems, Inc. deserve
special thanks, since they actually paid me money to port this code to
System III.
