--unit
is a number in the range 0-3 specifying which serial port to use; default is 0, which corresponds to the port often called COM1--port
is the I/O port where the UART is to be found; if specified it takes precedence over unit--speed
is the transmission speed; default is 9600.--word
and--stop
are the number of data bits and stop bits. Data bits must be in the range 5-8 and stop bits must be 1 or 2. Default is 8 data bits and one stop bit.--parity
is one of ‘no’, ‘odd’, ‘even’ and defaults to ‘no’.
The serial port is not used as a communication channel unless the terminal_input
or terminal_output
command is used.
