Internal Command
The CTTY command directs input and output to a different device other
than your computer’s standard keyboard and monitor.
Syntax

console.
The CTTY command only affects communication with ROM-DOS and with
programs that work through ROM-DOS for input and output. For
example, BASIC uses standard keyboard input regardless of previous
CTTY command usage.

CTTY COM2
Sets the device on COM2 as the input/output device.
CTTY CON
Returns control to the standard keyboard.
