Serial Port Expansion Card for Linux?

[Kenneth Burgener]

Hi,

Has anyone successfully used a serial port expansion card with Linux 
(specifically Red Hat)?  What brand and model did you use?

I have several network (ie. cisco, brocade, netgear) devices that have 
serial management interfaces that I would like to manage with a Linux 
server (in an emergency).

I was thinking something like this would work great, if it would be 
correctly recognized by Linux:

  SIIG Four 16650 serial port I/O card with 4-port (DB9)

Suggestions, ideas?

Thank you,
Kenneth
