RS232 monitor
Using this simple software, you can monitor and control any hardware compliant with RS-232 protocol, RS-485 protocol, RS-422 protocol or any other compatible serial port device. The RS-232 (DB9) pinout specifies that only the TX and RX pins are necessary for communication. The rest of the pins are necessary only if you implement some form of hardware flow control. You can read data from RX and send data to TX using Vovsoft Serial Port Monitor.
