control any more, and the speed of changing DTR isn't really an issue. Also,
the old code created a bug where zsparam() might have failed to set some
registers.
Change the interface to zs_hwiflow(); just have it use zst_rx_blocked.
Make zs_modem() a tiny bit faster.
Do RTS updates immediately; do not allow them to be held.
always located at the end of onboard RAM. This allows locore.s to zero
any offboard RAM to initialise the parity bit which most VMEbus RAM cards
have. Without this, many cards buserr on the first read access.
Thanks to Herb Peyerl for the idea.
Stop output as fast as possible when DCD is deasserted.
Do *not* automatically drop DTR when DCD is deasserted.
Only check for rr0 bits that we care about (DTR and DCD).
Make sure we turn on DTR and/or RTS as appropriate during open.
Rearrange close sequence so the tty is flushed before turning off interrupts.
Deal with `softcar' and the console device by silently asserting CLOCAL and
|HUPCL, as in com driver.
Do *not* fiddle with DTR when changing the line speed.
Make sure we update the tty's carrier status when CLOCAL or MDMBUF is changed.
Only change rr1 when we actually need to turn on or off TIE.
statfs() or getmountinfo() did not tell about the freshly mounted
ramdisk.
XXX Imo, "mount_mfs" should not return before the mount is done.
This is the only place where this can be done cleanly. But this would
require a substancial restructuring of "newfs". For now, wait in "mount"
until the filesystem appears.
where a remote completion or `mget' would confuse the client a `restart'
had been issued beforehand. now, `restart' is remembered until an operation
that can actually use it is invoked.
* in sendrequest(), don't reset restart_point upon entry. fixes `restart'
for `put' operations.
* if `restart' is invoked with no arguments, print current setting instead
of displaying a usage
* consistently use printf("%qd", (long long)restart_point) when displaying
restart_point
* use strto[lq]() instead of atol() when parsing `mark' and `restart' values
* remove unnecessary strlen()s when result of previous snprintf() will do
* replace a few malloc()/strcpy()s with strdup()s
* use SECSPERHOUR instead of '3600'
- use fgetln() instead of fgets()
- store info in internal buffer
- fix \\ support
- count line numbers internally, so \\ lines don't mess up count
* ypdb_store():
- ensure that the length of key or val doesn't exceed YPMAXRECORD
* makedbm, mknetid, revnetgroup, stdethers, stdhosts:
- improve error handling
- take advantage of rewritten read_line(), and cleanup line parsing
- don't print trailing ` ' for key/val pairs with an empty val
* Makefile.yp:
- fix up building of ypservers (from Chuck Cranor)
* ypinit.sh:
- remove leading spaces in variable assignment (from Chuck Cranor)
"verbose" mode after printing the exec args.
This invalidates most of my comment in the previous commit. (Not all,
there are still bogosities with mount_mfs.)
check all mounts (getmntinfo), not only the top one (statfs).
Otherwise we might miss lower level mounts on the same mountpoint.
XXX "mount" behaves differently with the "verbose" flag (-v) in some
cases, probably due to asynchronous calls to fs dependant mount programs.

Kazumasa Utashiro notes that the pmax cacheflush routines don't work:
#ifndef NOTDEF /* I don't know why Ralph's code doesn't work. KU:XXX */
It's because pmax hardware wries the COP0 bit to external branch
logic. news3400s don't, and so the bc0f loop fails. It will also
fail on some other models of pmax, but we dont' support them.
Surround the relevant framgents in locore_r200.S with "#ifdef pmax".
Longer-term, the cacheflush entry in the locore callback may have
to be a CPU baseboard-specific entry, not just CPU-version specific.
to 4.3BSD-style (BSD uses whole disk, 8 partitions, c=RAW_PART, d=/usr).
Initialize variables appropriately.
May be a good starting template for sparc, vax, others?
Use symbolic defines to allow changing the partition used for /usr (to
add a /var partition, or for consistency with i386).
