enter all commands characters ( will be entered by Enter key, that key sends also , but this
char will be ignored by commands parser).

party controllers requires the coding of some characters in a special
form (such as \X##). With most 3

party units there is a way to enter all ASCII characters so it is
possible to send all the commands also from the controller.

Some commands have a short name syntax beside the full name to allow faster typing, response is
always in long syntax.
