[BC] Re: Long serial connections

[Jeff Carter]

This was my solution:

It cost me about $35.  You use the included software to give it a
fixed IP address, and put it on your network.

The software also creates a virtual port that makes it look as though
the unit is attached to your computer as a regular COM port.
Hyperterm and all other software that expects a serial port will see
it as a normal port.

I use it to control/program/change the macros on a remote system
controller.  If you have a way to make it routable, the serial device
could be on the other side of the world so long as network latency
didn't kill you.

P.S. Not involved with this company, just really satisfied with the doodad.
