[WriteLog] serial interface PCI expansion boards

I have two of the Byterunner PCI-410HSP-9's.  They are PCI cards, use a
single IRQ and have 4 serial and 1 parallel ports.  Just for a test I put
both of them in a single PC so that I had a total of 10 COM ports (the
mainboard has 2 of its own as is common) and 3 parallel ports (1 on the
mainboard).  I tested all of the ports, they all worked.  I did not test in
5 bit mode for direct FSK as I am not running soundcard fsk, rather I am
using a PK900 for that.

I did ask the guy at Byterunner this card supported 5 bit mode and he said
it does....however I would test it myself before I believed it.

The additional ports (8 coms and 2 parallel ports) use a single IRQ (=9).

You might want to check  http://byterunner.com  and call their technical
service line, you will probably talk with  'Sean' (he has answered every
time I have phoned--could be a one man operaton) and put him on the spot on
the 5 bit issue.  Ask him to guarantee it will work or money back and test
it yourself and let us know one way or the other.

PS--Don't buy ISA cards....they are dying!!!
