I've just installed two identical fax modems into a Windows Server 2003 Standard server and for whatever reason, the first one works fine and the other doesn't. They both create virtual COM ports and using SysInternals PortMon, I can see that commands are being sent to the first modem okay, but nothing is sent to the second modem (even though the application attempts to communicate with it -- and fails opening the COM port).
I've seen lots of posts about this type of issue online, but I can't find an explanation for why I can't have two identical modems working side-by-side, or whether it is, or is not possible.
The second modem's going back if I can't get it working.
