Test RS232
This page can be used to access RS232 bus.
If you click on the "Connect to RS232 TCP Port" you can send ASCII data to
RS232 bus and receive data from it (only ASCII is visible in this application).
You can check "Add LF", "Add CR" and/or "Add Null" boxes to add a Line
Feed, a Carriage Return and/or a Null Byte at the end of the ASCII chain
sent to the device.
