Remote Command Set

Command Syntax

The 8742 Controller/Driver utilizes an ASCII command set and also outputs system
status in ASCII format. Commands may be either upper or lower case characters.
The diagram below illustrates the 8742 controller command syntax. As indicated in
this diagram, a valid command consists of three main fields. The first field consists
of a numerical parameter "xx", the second field consists of a two letter ASCII
mnemonic, and the third field consists of numerical parameter "nn". The command
is finally terminated by a carriage return. For example, 3PA10 is a valid command.
If a command does not require parameter "xx" and/or parameter "nn", that field may
be skipped by leaving a blank character (space). For example, 1DH, and VE? are
valid commands.
Multiple commands can be issued on a single command line by separating the
commands with a semi-colon (;). For example, "3VA1500; 3PA1000" is a valid
command line. If a command line has multiple query commands, the response string
from the controller will have responses to all the query commands in the command
line. Each response in the response string will be separated by a semi-colon. For
example, the response to "3VA?; 3AC?" command can be "2000; 30000". In this
example, the value 2000 is a response to 3VA? command, and the value 30000 is a
response to 3AC? command.
