Additional Comments
Expander triangle

Use the COM4: keyword to communicate through the COM 4 serial port.

Comments:

To set the port parameters (such as baud rate, handshaking, and parity), set the serialControlString property before opening the port with the open file command.

To read data from the COM 4 port, use the read from file command, specifying the keyword COM4: as the file to read from.

To write data to the COM 4 port, use the write to file command.
