OK Paul, but a *normal* standard serial port card has two 16550xx UARTs a
two connectors. These cards are AFAIK not able to share interupts
correctly. It works sometimes, when you don't use the corresponding port
at the same time, but this is not my thing. And if you have a
AMD-586DX/120 in an old VESA local bus motherboard, it could be
impossible (like it was for me).
Now for something completely different!
You talk about a JDR Microdevices card with 4 ports. is it supported by
linux??? How much does it cost??? Because I could use some more ports at a
communication box at work, which should run Debian, if everything goes
right.
Thanx in advance!
