Appendix F
Maintenance Port Parser
Commands
TracVision LF/SF system parser commands are parsed when the
system receives an ASCII carriage return (Hex 0D). An ASCII line
feed (Hex 0A) is permitted but is ignored in any transmitted
command. All system responses are terminated with an ASCII
carriage return followed by a line feed and ending with either an
acknowledge character (ASCII > (Hex 3E)) or a not-acknowledge
character (ASCII ? (Hex 3F)). The parser commands are shown
below in boldface capital letters but they are not case-sensitive. In
most cases the command is responded to with an echo; that is, if
you type
ZAP, for example, and press “ENTER,” the response will
be the command you have entered (i.e.,
ZAP). For other commands
the response is specific for each command, such as
VERSION,
STATUS, or HELP.
