[Trlog] LPT Woes...

[Pete Smith]

This reminded me -- once, when I installed a serial port card, the driver 
that came with it seemed to derange the operation of LPT port 14.  On 
another occasion it was the driver that came with a parallel port 
scanner.  So Brett's idea about the cause being not TR-related seems to 
make sense to me.
