[WriteLog] WriteLog, shared IRQs and COM ports

[Ron Stordahl]

PCI  cards and interupt sharing have solved the conflict problems.  I have 2
4-port Byterunner PCI cards( which also each include 1 printer port), so
including the on board serial ports I have a total of 10 com ports and the 8
Byterunner ports plus 2 LPT ports all use the same IRQ-11 (plus I believe my
sound card and my network card!).  I have unused IRQ's!   I have tested this
with both Windows ME and Windows XP.
