Here is a simple one (I hope). Does anyone know what the maximum speed is for sending and receiving on Sparc-Station 1+ or SLC? I seem to remember the old Sun-3's rated at 9600 for two way communication, and 19,200 in send only. I would like to use 38k modems for running cslip between two sites, and I can't seem to find the maximum baud rate for the Sparcs in the reference manuals. Any help would be rgeatly appreciated.

Look in <sys/ttydev.h>, which shows B38400 as the maximum, at least under
4.0.3c and 4.1.1. We run PPP at that speed with fine results. On a
Sun-4/60 (SPARCStation-1) running 4.0.3c and with two T1600s attached,
things look like
8:59am> eeprom | egrep ttya
ttya-mode=38400,8,1,n,h
ttya-rts-dtr-off=false
ttya-ignore-cd=false
8:59am>
My /etc/ttytab entries are simply
ttya "/usr/etc/getty std.38400" unknown on # in/outbound PPP
where that gettytab entry looks like
h|std.38400|38400-baud:\
:sp#38400:nx=std.19200
My devices look like
9:01am> ls -Failg /dev/{cu,tty}[ab]

This may be more detail than you asked for, but I hope it's useful.
