The RIM-1000 supports a Telnet connection over IP port 23. When properly configured a Telnet user can use the Com1 port of
the RIM-1000 to communicate to external EIA-232 enabled devices.

The Com1 port is located on the back of the RIM-1000. The COM1 Transmit and Receive LEDs are also located on the back of the
RIM-1000.
The EIA-232 port allows communications between the RIM-1000 and one other device (point-to-point connection). The EIA-232
