[TRLog] Splitting a serial port

With some help from Bernie, ZS4TX, I managed to install the Eiger Labs PCMCIA Serial card on my IBM ThinkPad T20 running Windows 95. The card installs automatically in Windows and seems to work quite reliably in DOS mode as well. I tried both Cardware 2.0 and CardSoft 3.1 for enabling the card in DOS mode. However, after hours of playing with different set-ups and trying to configure the memory both "manually" and with the help of Memmaker, the best result was only about 520 kb of free memory. I believe this not sufficient for reliable operation with bigger contests, especially with the SCP and master database enabled.
