Porter Commands
The command codes shown below control various functions of the Porter. All codes
begin with a user defined prefix that is 1-6 characters long. Zero (null, not ASCII “O”) may
not be used as part of the prefix. The prefix can be stored in non-volatile memory to
become a semi-permanent part of the control codes. The prefix should be chosen so as
not to interfere with other control codes used in you equipment. The purpose of the
prefix is to uniquely separate the code from the data you are transmitting. The factory set
prefix is 27,64 (the two characters ESC,@).Following the prefix is a one character
command and optional operands. The 8 th (high) bit is ignored when setting a new prefix
or checking for an incoming prefix on port 0.
The + signs under “Code” are for illustrative purposes only. Do not use them in the
command string. All command letters are case sensitive – use upper case letters only.
