Using a shared COM port for an External Modem on Microsoft Virtual Server 2005
Posted on 2007-10-17
We are running Microsoft Virtual Server 2005. We are trying to run an external USR Modem off of the external COM1 port via a seriel cable.
The modem works fine when we go to use it through the physical server. The problem is when we go to map the virtual com port in the virtual server, the port maps but it won't auto detect the attached modem. I can manual create and install the modem. I can send commands to the modem, but when I try to dial with the modem it gives me en error stating the device is not available, attached or functioning properly. (Error 680 I believe, I'm stuck waiting for a down time to reboot due to to many hardware changed right now, so I can't pull up the exact error, sorry :) )
Also, once the com port is shared to the virtual server, the physical server will give the same error when trying to access the modem. I followed the instructions on technet and msdn regarding sharing of com ports with MS Virtual Server but to no avail. I was wondering if anyone has gotten this to work and how it was done. Thank you.
