USB-Based Serial port Modules

[Martin McCormick <martin@dc.cis.okstate.edu>]

	I have been meaning to buy a serial port module to connect to
the USB port on a Debian system.  I should have bought the Edgeport
8-port module when I saw it for sale early this year, because
Pricewatch shows only a 4-port model available now or a 16-port unit
for $600.  Are there any other options?  Four ports may not be enough
for the various projects I have, but 16 is a bit much at least at $600
when I had planned to spend around $300.

	I just need to be sure that it will work with the 2.4 kernels.
