Modem Connectivity Issues with SEP installed
My company has moved to SEP for virus/spyware control, and the IT manager asked me to set up two systems which are running specialized applications, and I've run into connectivity issues with both of them. I was able to resolve the first one, which receives medical data through the HL7 format over a VPN connection (by only installing the virus scanner), but I'm not having any luck finding a solution for the remaining system.
The problem system connects to a hospital mainframe through an old, dial-in system. This program connects to the modem directly through the COM port, DOS-style, and there's no user-adjustable options. We have a 56k US Robotics modem hooked into Com 1 - the program is so specifically coded that we actually had to track down a specific brand of US Robotics modem when our old one bit the dust!
With the SEP antivirus installed, the program is no longer able to pick up the modem and dial out. It appears to be able to communicate with the modem, as the SD/RD status lights flash, but once it gets to the point in the process where it would send the ATDT command, nothing happens. Once I uninstall SEP and reboot, the program works again... until I reinstall SEP, at which point it immediately fails again.
Are there any configurations I haven't located which would explain this behavior and allow me to resolve this issue?
