# Description

Use the printer: keyword to communicate through the printer serial port.

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 printer port, use the read from file command, specifying the keyword 'printer:' as the file to read from.

To write data to the printer port, use the write to file command.

To use the modem port on Mac OS systems, use the 'modem:' keyword. (LiveCode does not support additional serial ports.) To use serial ports on Windows, use the COMn: through COMn: keywords.
