SIO or COM.SYS will not see the LT port as the the LT driver provides
that service. The rest of what you see is all too familiar to me.
First, I see a COM1 (3f8:4 should be the traditional COM1) as well as
a COM2 (2f8:3) . That means that there are 2 COM2's there - and I
suspect that the LT modem is loaded after the SIO/COM line. You can
disable the COM2 (2f8) in the BIOS or try changing the assigned port
to com3. SIO will allow that altho COM.SYS is a PITA in that it
damned well insists that if you have 2 serial ports than the first is
com1 and the second is com2 and don't try to tell me any different! I
looked at the server setup where I installed the LT modem and found
that I had tried two different setups: 1st disabling the onboard com2
in bios, then by tellign SIO to use com1 and com3 with the specified
serial port addresses while leaving com2 unused in the SIO line
(COM.SYS ignored me here). Apparently, both worked but the result I
have in use now has the port disabled in the bios. You will have to
work around the conflict in assigned port names - that was the
conflict I was referring to.
