4.3 Commands Entering
If a terminal software is used to connect over serial \ ethernet \ USB port, it is possible to directly
enter all commands characters (
will be entered by Enter key, that key sends also
, but this
char will be ignored by commands parser).
Sending commands from 3
rd
party controllers requires the coding of some characters in a special
form (such as \X##). With most 3
rd
party units there is a way to enter all ASCII characters so it is
possible to send all the commands also from the controller.
4.4 Commands Forms
Some commands have a short name syntax beside the full name to allow faster typing, response is
always in long syntax.
4.5 Input String Max Length
