Very informative replies. Thanks

We actually have used the USB-USB network bridge (the purple USB 1.1
version from Laplink). While they had
their usefulness for a previous purpose, I am not sure if they will
work for this case, unless we do use a serial to
IP redirector in conjunction with this device. If that is the case the
laplink USB-USB network bridge wouldn't be
needed.

Would it be possible to piggyback two of these USB to RS232 devices
together so that each end would have the
USB connction, then connect the two DB9 connectors together. Would
this present a major conflict or could the
device data be transferred both directions? Just a thought.


Sure. Either idea will work. The "blob" idea offers high thruput,
but requires the right software to get it to work. (I don't know
if USB.org has defined an official class definition for the thing
or not.)

The USB-to-serial idea has the advantage that it looks like a serial
port, so more software may work with it. Just make sure you use the
right DB-9 to DB-9 cable to connect them together, and that the
devices have the feature set you're looking for (hardware flow control,
high baud rates, or whatever).

You can get some pretty fancy ones.
