I agree that no additional h/w is better (in general). I thought that
Jason Stahls made the comment that would imply "you shouldn't trust a
USB serial chip". Since I have a production application that in fact
does trust a USB serial chip, I'm curious as to why I should be
"nervous" and what I should be looking out for. Like I said before,
we are using the USB-COMi-M w/ seemingly great success so far.

You don't need to do any usb specific programming. The device shows
up as a standard serial port, typically as something like /dev/
ttyUSB0 or on the ts7300 as /dev/usb/tts/0. Then just do *normal*
serial port programming -- you will of course need to make provisions
for getting the custom / high speeds but that doesn't have anything
to do w/ USB (at least from the programming perspective).
Anyway, good luck. This page may also help you ... especially the
section on "Non Standard Baudrates".
