PORTER INSTALLATION AND OPERATIONS MANUAL

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

(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.
