Subject: PC-Term direct-wired via Serial Port?
Date: Tu, 09 Feb 1999
From: imgfac@gate.net
I have a Digiboard "dumb" 8 port multiport card (PC/8) installed in a
FBSD 2.2.8 box, correctly configured and showing all ports, ports test
fine for dial out via modem and dial in via modem (all ttydx, cuaax and
related /dev files created and in place).
Okay. I wanted to direct-connect a 386 PC via a null modem cable (see
FBSD Handbook section 14.2.2.1 Cables) connected to the com1 (db-25) PC
serial port (at 2400Bd according to the MSD diagnostic Utility) and
connected to the third serial port of the digiboard octopus cable
(db-25). I am using qmodem 4.6 comm s/w as a terminal emulator
configured as vt100 at 2400Bd 8,n,1, but I cannot get any screen on the
PC, not even if I switch term
emulation from vt100 to TTY at same baud, etc. In ttys (on the Unix
machine) I have the serial line configured thus:
ttyd3 "/usr/libexec/getty std.2400" vt100 on secure
This port shows up with command: ps -ax in the PID list
I have also played around with the term identifier changing it from
vt100 to dialup, just to see if it made a difference. It did not. I do
not get a login prompt on the pc/term screen. A db-25 line fault tester
indicates traffic on the cable from the pc to the unix box but i do not
get a login prompt (or did I say that already?)
I have read and re-read the various man pgs and hbk and faqs, but Surely
I am missing something here. This is a new installation and I am a
new-bee (to FBSD). So folks, what am I missing or should I do to get
this exercise home? Please do not suggest a switch to mgetty as I first
need to finish with this issue.
An e-mail reply would be preferred.
thanks,
.if.
P.S. my stty -a -f output looks like this:
speed 2400 baud; 0 rows; 0 columns;
lflags: icanon isig iexten echo echoe -echok echoke -echonl echoctl
-echoprt -altwerase -noflsh -tostop -flusho -pendin -nokerninfo

cflags: cread cs8 -parenb -parodd hupcl -clocal -cstopb -crtscts

-dtrflow -mdmbuf
cchars: discard = ^O; dsusp = ^Y; eof = ^D; eol = ^[; eol2 = <undef>;
erase = ^?; intr = ^C; kill = ^U; lnext = ^V; min = 1; quit = ^\;
reprint = ^R; start = ^Q; status = ^T; stop = ^S; susp = ^Z;
time = 0; werase = ^W;
maybe the answer is in there somewhere.
P.P.S. what da heck is ttyh0? MAKEDEV wont make it but it appears in
the man page for ttys under v2.2.8.
