The Telestar 121 terminal
has an internal microprocessor with suitable software
for entering, storing, correcting, deleting, sending and receiving messages.
The system is controlled by means of commands that are entered via the keyboard.
Each command is started with the COM-button, followed by a single letter
(the actual command) and one or more comma-separated parameters. It
is terminated with the ↵ (ENTER) or EOF key.
Parameters in square brackets [ ] are optional.
The following commands are recognised:
