Add a program that matches the pc532 ROM monitor download command.
This source will be part of the distribution. It also is hacked to be on the receiving end as well as the sending end. This includes a CRC check, but no retransmission. This will remove any reference to kermit in the pc532 distribution because this program can be used to get the distribution sets onto a pc532 over a serial line.

|

/*
|
||||
Hacked by Phil Nelson for use with NetBSD, 10/5/95.
|
||||
This source is in the public domain except for the makeraw function.
|
||||
|
||||
The upload part of this program is taken from Bruce's ROM debugger
|
||||
code.
|
||||
|
||||
For NetBSD, the usages are:
|
||||
|
||||
download file
|
||||
- open "file" and ship it out standard output with the
|
||||
format expected by the pc532 ROM monitor download
|
||||
command.
|
||||
|
||||
download -r nfile
|
||||
- standard input was generated by a "download file" command.
|
||||
Capture it, checking the CRC and store it in "nfile".
|
||||
|
||||
|
||||
Note: This program uses termios.

Here is the download program which I run at the other end of the
|
||||
serial line -- in my case, on an AT clone. The download protocol
|
||||
is explained in the comments in the program. I just recently added
|
||||
the download command to the monitor so let me know if you have
|
||||
problems with it or if you wish it worked differently.

/* Download protocol:

*
|

* <start mark> <length> <data> <CRC>
|
||||
*
|
||||
* Below, the sending machine is called SRC, receiving machine is DST.
|
||||
* Eight bit characters are used.
|
||||
*
|
||||
* Control-C (0x03) aborts the transfer. This capability is nice
|
||||
* to have if, for example, length is garbled and the DST expects
|
||||
* billions of characters. Since any byte of <length>, <data>,
|
||||
* or <CRC> could be control-C, we need to have a quote character.
|
||||
* I use ESC (0x1b). Thus, control-C and ESC are sent as
|
||||
* {0x1b 0x03} and {0x1b 0x1b}, respectively.
|
||||
*
|
||||
* Start mark:
|
||||
* This is a colon. When SRC begins sending, DST loops until it sees
|
||||
* the start mark. Thus, if spurious characters are sent as the
|
||||
* user switches from terminal emulator to download program on SRC,
|
||||
* DST can ignore them.
|
||||
*
|
||||
* Length:
|
||||
* Four bytes, least significant first. The length is number of
|
||||
* data bytes to be transfered, not including quote characters.
|
||||
* The two CRC bytes are also not included in the length.
|
||||
*
|
||||
* Data:
|
||||
* A byte is sent as a byte, with quoting if necessary.
|
||||
*
|
||||
* CRC:
|
||||
* Two bytes, least significant first. Use CCITT CRC generator
|
||||
* polynomial (x^16 + x^12 + x^5 + 1). Compute on data only (not
|
||||
* length or start) and exclude quotes. (This is the same CRC
|
||||
* as computed by Minix's CRC command.)
