Digiboard Experiences (Mini Howto?)
Just to share some experiences from installing a Digiboard
on a linux system (redhat 3.0.3). (might come in handy sometime)
The Digi refered to is the most newly spoorted X/R intelligent async port
supporting 115000 speed on each port.
(Costs about $1150 for an 8 port if anyone is interested).
The latest driver from Digi is the only one that works, beta's had lots
of problems.
Once you patch the kernel and cfg the device (using Digi's cfg software)
you can test to see if the thing works.
1. The straight-through cables HAVE TO BE with all the wires. If you buy
the cheap cables with only 2,3 and some other connected - NO GO.
Hint: if you doubt your cable, simply plug the modem into the device.
2. If you got past this you can test access to the modem using the "cu"
command:
cu -l device_name dir
modem ctrl devices are cudx
giving atz/ats0=1 or such commands while in cu should let you see if the
modem is receiving commands.
If not you can check if its the Hardware/modem problem
by shortening between cables 2 & 3 on the port and piping it's output to
STDIN:
$ cat < /dev/cud3 &
$ cat /etc/passwd > /dev/cud3
When shortened, you should see the output to cud3 on your screen.
3. give the modem an ATS0=1, AT&W0 and plug it into the digiboard.
4. mgetty gives the best logging and options for the dialins - use it.
(using getty on an SCO from lack of alternatives was the reason for
failure).
/usr/local/sbin/mgetty -x 9 -D cud3
in the inittab should do it.
5. if all works, you should be able to login to the system
6. dynamic_ip schemes for PPP are reccomended in the ISP howto.
7. get Dial-Up_Utils_2.23.tar.gz from the Serial dir at sunsite.
This lets an admin ctrl time limits for logged-in users, as well as
expiring accounts automatically and more goodies.
