Using PComm

The PComm Diagnostic program is a very useful tool for checking the status of MOXA’s multiport boards. It provides internal and external testing of IRQ, TxD/RxD, UART, CTS/RTS, DTR/DSR, etc. This program can be used to make sure that MOXA’s boards and ports are working properly.

To start this program, click on Start " Programs " PComm Lite 2000 "PComm Diagnostic.
