Dale,
It is do-able! I am working on a prototype of almost the exact same configuration. You need to setup your ltsp scripts to load the "serial" module into the kernel, and you also need to insert the following lines into the /opt/ltsp/i386/etc/devfsd.conf file:
REGISTER tts/.* PERMISSIONS root.root rw-rw-rw-
REGISTER cua/.* PERMISSIONS root.root rw-rw-rw-
Which will give you permissions to write to the ttys.
Depending upon how far you have gotten into this project, the next step may not make sense. To send the dial string to the modem, you need to be able to write to the device (/dev/ttyS0, for example). In order to do that, you need to have a session on the physical workstation that has the modem connected. In order to do that, you need to be running the LTSP 'local apps' package. With 'local apps' enabled, you can rsh to the workstation and execute the command to dial the modem. Your other option would be to actually run the whole application as a local app, but in my situation, rsh makes more sense.

SUBJECT: [Ltsp-discuss] Runlevel 3, local modem & lynx I have about 50 workstations that currently boot from a DOS boot disk
(floppy) into a Novell server. These use a legacy DOS app that is basically
a database of phone numbers to dial and then records the data entered after
each dial. Each workstation has its own modem connected to its own phone
line which then routes through our PBX.
I want to use LTSP to get rid of all this! My plan was to have each
workstation log into an LTSP server and then each workstation would have
access to our internal web/mysql server to get the phone numbers. So, as I
have been putting this together, I have run into a couple of problems:
How do I initialize a local modem?? If each workstation has a "/dev/ttyS1"
do I somehow create a separate root environment for each?? Maybe I need to
use runlevel 3 and use lynx as my browser? If I can use a serial mouse on
each workstation then it makes sense [to me at least ;\] that it would just
be another serial device...??
