Dear Alpha Unix Managers List,
We are just trading our ancient 2100 for a slightly less old 4100 on
which I've just loaded 4.0E. The 2100 ran two modem lines setup for ppp
off the two stock serial ports on the back of the box, tty00 and tty01.
This worked like a charm, and now we'd like to do the same on the 4100.
We seem to have some big (hopefully simple) problems that I haven't
solved after scanning the archives dating back to early '96.
(1) We do not have /dev/tty00 or /dev/tty01 (!). When I try to make
them with "/dev/MAKEDEV tty01", etc., they do not get created. I've
set the SRM console-level variables for COM2 (tty01?) as follows:
set COM2_FLOW hardware
set COM2_BAUD 57600
set COM2_MODEM on
This does not solve the problem; after reboot I still don't get any
/dev/tty00 or /dev/tty01 and can't MAKEDEV them. Is there some other
SRM variable I have to set to get the machine to see the serial ports
at boot time? We have other stuff set as before on the 2100, such as
modem1:23:respawn:/usr/sbin/getty -h -t15 /dev/tty00 M115200 vt220
modem2:23:respawn:/usr/sbin/getty -h -t15 /dev/tty01 M115200 vt220
in /etc/inittab, and other stuff. But clearly I'm not getting that far.
(2) Related to the above, I've seen in the archives that modems "don't work"
on the COM1 port of the 4100's. When I try to set COM1_FLOW similar to
COM2_FLOW above, I get some warning about overriding the embedded
console. And when I try to set COM1_BAUD to something other than 9600,
it refuses and tells me I need Serial ROM V2.0 or greater to support
alternate baud rates. Is it possible to swap in a new ROM chip to get
V2.0 or above, and does this solve the "problem" with modems on COM1?
If it can be done, does anyone have a part number?
(3) The 4100 has a "modem" port just to the right of COM1/COM2 and just
below the parallel port. Can this "modem" port be used for a standard
dial-in modem? Also there is a 12V power connector to the right of the
COM ports and mouse/keyboard connectors; what is that for?
(4) Does anyone know of a PCI multiport serial card that would give me
a couple of extra serial ports functional for modems on the 4100?
A DEC/Compaq part number or vendor name would be appreciated.
Thanks, Jay P.
