AccuTab II 44
Command Mode Basics
To enter GTCO CalComp by Turning Technologies Command Mode:
Send an ASCII CTRL-A (hex 01) character to AccuTab II. When AccuTab II receives the CTRL-
A, two things happen:
 Digitizing stops and new coordinates are not generated. If Command Mode is
invoked during transmission of a coordinate, that coordinate transmission will be
completed.
 AccuTab II sends a “>” (hex 3E) as a prompt to the commanding device. AccuTab II is
now ready to accept commands.
A command consists of two upper case ASCII letters or numbers followed by a delimiter.
The delimiter lets the AccuTab II know the command is complete. There are two kinds of
delimiters:
 <CR> (carriage return, hex 0D): indicates end of current command and more
commands will follow. If the command just sent is valid, it will be carried out. The
AccuTab II then sends another > prompt and awaits the next command.
 <ESC> (escape, hex 1B): indicates end of current command and no more commands
will follow. If the command is valid, it will be carried out. Then AccuTab II will exit
Command Mode and return to Digitizing Mode.
If you are entering several commands, end each one with a carriage return delimiter. After
each <CR>, the AccuTab II carries out the command and sends a new command prompt.
After the last command or if you are entering only one command, use an <ESC>. The
Escape delimiter takes you directly back to Digitizing Mode.
