I just went through the same experience a few weeks ago. I have a SO2R
setup with 2 serial and 2 parallel ports being used by TRLog. COM1 and
LPT1 are on the motherboard; COM4 and LPT2 are plug-in ISA boards.

Is the new LPT port PCI or ISA ? There are probably jumpers on the
board to set the address - make sure it is set to LPT2 (address hex 278).
When the computer is booting up, there is a screen that appears briefly
that shows all the serial and parallel ports detected by the BIOS. Make
sure both LPT1 (address 378) and LPT2 (address 278) are shown.

I had no trouble running TRLog from a DOS window under Win 98. Make
sure that no other Windows application is trying to use the serial
ports. Also, go to Settings->Control Panel->System->Device and make
sure the serial and parallel ports are detected by Windows.
