[net.micro.pc] A Second Serial Port?

I have a need to add a second serial port to my PC.  Presently I have a
Quadram Quadboard so I am not particularly interested in multi-function
cards unless they offer memory, serial port, and a function not included
on the Quadboard.

Can anyone suggest the best alternative for a second serial port?  Cost
is somewhat of a consideration.  Thank you.

John
