5275513295 Fix some outstanding bugs in the DCD modem control..
Implement the slip/ppp "hotchar" detection to improve latency
Debug the L_RINT bypass code..
Fix an interesting feature that caused 8-bit chars to loose their top bit
in some circumstances..

This finishes the remaining outstanding problems that I'm aware of, with
the exception of efficiency...  Optimizing can come later after it's fully
debugged.

d3497bc8de add a new Debug mode.. "DBG_OPTIM" - for observing the L_RINT bypass 1995-08-22 00:42:07 +00:00

1cf4903ecd Slight change to the location of the default termios flags to make them
a little easier to change, and revert to the "standard" specialix behavior
with CRTSCTS enabled in the initial cflag (but configurable).

bb65956af3 Next round of cleanups. Some more debugging hooks added, si_softc definition
moved to the driver proper, so that <machine/si.h> can be #included by user
programs without needing to include stuff from /sys/i386/isa..
Various (now) redundant features removed, eg: the locks on IXANY and HWFLOW
as these are now done with the "initial" and "lock" termios devices.
Note that it still (for reasons unknown) appears to be masking data to
7-bit with ppp - hence the cleanup to support the debugging via 'sicontrol'

f64003830d Remove a deliberate #warning.. It's not polite, because I listed the the
driver in i386/conf/LINT...

b77990be3e Bring in my long-overdue version of the Specialix driver.
This was originally ported to BSDI by Andy Rutter <andy@acronym.co.uk>.
At the end of the day, this code has very little in common with Andy's
version, or the Specialix SYSV version.  Essentially it has been gradually
and almost completely rewritten, with LOTS of advice and inspiration from
Bruce Evans.  There are a couple of missing bits still, but they are minor.

The user-mode "sicontrol" program is in sad shape and will come in soon.
Transparent printing died a timely death.. Maybe later..

Jeremy Rolls @ Specialix (Development directory) has confirmed this is OK
to distribute, and Andy personally sent me his version that I started from.

Although this driver stood up to a nasty stress-test in this form, I am not
confident that there are no nasty bugs lurking.

People are welcome to try it, but dont go out and buy one just yet.. :-)
And *DONT* use it on a mission-critical machine... This is ALPHA QUALITY!
