I have an IBM RS6000 F80 model running as an AIX server onsite (AIX 4.3.3.0). Can anyone tell me if it is possible to configure the Service processors Call in/Call Out functions to use a modem via a terminal server. i.e. the connect would be from AIX server serial port to terminal server port, the modem for Call in/Call out would be attached to another of the terminal server ports. I don't see Call in being a problem as the caller can issue the required "connect" commands in the Terminal server, I am more concerned about Call out. Any ideas ??

If you manage to make the terminal server do an automatic connect/dial when the SP starts a conne connection you should have no problems. Also, if the outgoing call gets connected automaticaly to the modem port.

You can get into problems if there are RS232 signaling problems (i.e. if the signal lines don't follow what the SP expects from a modem).

Either way, IBM will not support such a configuration (no help) but if you manage to make it work, they won't complain either. :-)

If you can force the call-in to pre-empt the call-out, you should arrange for the incomming and outgoing lines to be separate.

If the terminal server doesn't support such a configuration, you must use the same modem for both call-in and call-out.

Either way, it will be a problem-prone setup (and HARD to configure/debug)

Unless you have a huge amount of machines, it would be a better option to have one modem per machine (directly attached).
