I have come to the conclusion that using a digiboard was not my best move.
I'm *still* trying to get these things up and running, without success. It
seems to me that I must be very close to the answer, but just far enough off
that it isn't working. So here is my plea to all kind souls out there to
please help me figure out what I'm missing...
My problem(s) is (are) this: No matter what configuration I set all four of
them to, they don't all act the same, and so far, none have worked properly,
not even once. What is strange is that D00 and D03 seem to work the same
and D01 and D02 seem to work the same. If I set all four to config 'A' then
D00/D03 will act one way and D01/D02 work another. Use config 'B', D00/D03
do something and D01/D02 do something else.
Yes, I tried swapping the modems and the problems follow the port, not the
modem. In fact, I got two pc's so I could test, and can get them set up so
that I can dial in or out to either machine from either modem. There were
still some wierdness here and there, but I could put both pc's into procomm,
go into 'host' mode and type away. I can set up the modems so they work
between the pc's fine, then plug them into the digiboard and have problems.
They connect, but nothing else happens.
So, here's the scoop. I wasn't sure what anyone would want or need, so at
the risk of a serious info overload, here's everything I think might have
anything to do with the situation.
* the server is a p133/128meg ram, 2.1gig scsi hdd, with fbsd 2.2 (via ctm)
* the digiboard (PC/8e) is physically installed in the server (not coming in
via the net from a terminal server box)
* I only have four modems at this time, so I am using ports 0-3 on it. The
modems are Practical Peripherals 33.4, and all appear to be identical.
* using the dgb device driver in the kernel, using this line to configure it:
device dgb0 at isa? port 0x100 iomem 0x0a0000 iosiz ? tty
* the digiboard seems to be found and recognized, per these bootup messages:
Mar 15 21:03:31 adam /kernel: dgb0: PC/Xe 64/8K (windowed)
Mar 15 21:03:31 adam /kernel: dgb0 at 0x100-0x103 maddr 0xa0000
msize 8192 on isa
Mar 15 21:03:31 adam /kernel: dgb0: 8 ports
* the device(s) were built using MAKEDEV, which generated the following:

ALL of them used to say uucp:dialer. What changes them is a mystery to me.
I know that from time to time I have to chmod rw-rw-rw- to make them usable.
But why they change in the first place is beyond me. I can say that if
cu/tip don't exit properly (using ^c insteaf of using ~.), then the perms
will be set to 600:root:wheel, but other than that, I'm in the dark...
* I added these records to /etc/ttys:
ttyD00 "/usr/libexec/getty std.57600" dialup on insecure
ttyD01 "/usr/libexec/getty std.57600" dialup on insecure
ttyD02 "/usr/libexec/getty std.57600" dialup on insecure

ttyD05 "/usr/libexec/getty std.57600" dialup off insecure
ttyD06 "/usr/libexec/getty std.57600" dialup off insecure
ttyD07 "/usr/libexec/getty std.57600" dialup off insecure
#cuaD00 "/usr/libexec/getty std.57600" dialup on insecure

cuaD05 "/usr/libexec/getty std.57600" dialup off insecure
cuaD06 "/usr/libexec/getty std.57600" dialup off insecure
cuaD07 "/usr/libexec/getty std.57600" dialup off insecure
cuaD00 "/usr/local/sbin/mgetty" dialup on insecure
#cuaD01 "/usr/local/sbin/mgetty" dialup on insecure
#cuaD02 "/usr/local/sbin/mgetty" dialup on insecure
#cuaD03 "/usr/local/sbin/mgetty" dialup on insecure
#cuaD04 "/usr/local/sbin/mgetty" dialup off insecure
#cuaD05 "/usr/local/sbin/mgetty" dialup off insecure
#cuaD06 "/usr/local/sbin/mgetty" dialup off insecure
#cuaD07 "/usr/local/sbin/mgetty" dialup off insecure
I got a suggestion to use mgetty instead of getty, so I compiled and
installed it from the ports area. As you can see, I'm testing one of both
(cuaD00 as mgetty and cuaD01 as getty).
* using various programs (cu and tip on fbsd, procomm on a pc), I have
configured the modems like this:
b1 e1 l3 m1 q0 v1 w0 x4 &b1 &c1 &d3 &g0 &l0 &p0 &r0 &s0 &x0 &y0
s0:001 s1:000 s2:255 s3:013 s4:010 s5:008 s6:002 s7:050 s8:002
s9:006 s10:014 s11:095 s12:050 s18:000 s25:005 s26:001 s37:000 s72:000
* and, finally, stty -a -f /dev/cuaD00 shows (all four match):
speed 57600 baud; 0 rows; 0 columns;
lflags: -icanon -isig -iexten -echo -echoe -echok -echoke -echonl
-echoctl -echoprt -altwerase -noflsh -tostop -flusho -pendin
-nokerninfo -extproc
iflags: -istrip -icrnl -inlcr -igncr -ixon -ixoff -ixany -imaxbel -ignbrk
-brkint -inpck -ignpar -parmrk
oflags: -opost -onlcr -oxtabs
cflags: cread cs8 -parenb -parodd hupcl clocal -cstopb crtscts -dsrflow
-dtrflow -mdmbuf
cchars: discard = ^O; dsusp = ^Y; eof = ^D; eol = <undef>;
eol2 = <undef>; erase = ^?; intr = ^C; kill = ^U; lnext = ^V;
min = 1; quit = ^\; reprint = ^R; start = ^Q; status = <undef>;
stop = ^S; susp = ^Z; time = 0; werase = ^W;
[side question: Isn't there a way to export the stty settings from one port
and add them to another? I remember doing something like this long ago but
don't remember how it was done. I tried "stty -g -f /dev/cuaD01 <
/dev/cuaD00", but it didn't seem to work the way I thought it should...]
So, my kind and dear friends, bearers of good tidings, singers of songs, and
general people of awesomeness...
What am I missing? Should this work as is, and I have hardware problems?
Am I still missing something? Am I even close?
Any pointers greatly appreciated...
