4.20 Switching channels by sending RS232 data
You can switch the LINDY CPU Switch Dual Junior remotely by sending RS232 data
to the serial communications port (located on the rear panel adjacent to the power
connectors). All data should be sent using the following RS232 protocol.
Baud: 19200, bits: 8, stopbits: 1, parity:none
No handshaking is implemented but valid command characters will be echoed back
to the sender.
The top nibble (4 bits) of the command byte defines the user port that is to be
switched (1=port 1, 2=port 2). The bottom nibble defines the computer port that the
user port is to be switched to (e.g. 0=port 1, 1=port 2, E=port 15, F=port 16).
For example:
Hexadecimal code 14 switches user port 1 to computer port 5
Hexadecimal code 28 switches user port 2 to computer port 9
Hexadecimal code

Hexadecimal code 72 switches user port 2 to computer port 0 (off)
