Optional Coaxial/Twinaxial Interface
Command Interpreter
A user friendly command interpreter has been built into the coaxial/twinaxial interface. This feature allows you to send any hexadecimal character or string of characters to the printer through the coaxial/twinaxial port.
The logical not character (__) used below may be shown as the carat (^) on some keyboards. Either character is usually the accessed as a
The command interpreter is enabled by receiving "__ONN" and disabled by receiving "__OFF". The default is "__OFF".
If enabled, the command interpreter examines all printable data received from the host for the string "__HEX" Once this string is found, then all EBCDIC characters following are converted to hexadecimal and sent to the printer. The conversion process is terminated by receiving an "@" character. Receiving any
Example: The following string will cause the interface command interpreter to send the ESC L n sequence (see the "Forms and Tractors" section in the Printek emulation chapter) to the printer to load form number two.
Turn the command interpreter on by sending __ONN
then send
__HEX 1B 4C 32 @
in which the hexadecimal character 1B is an Escape character, the hexadecimal character 4C is the ASCII character "L", and the hexadecimal character 32 is the ASCII character "2".
The command interpreter should now be turned off by sending
__OFF
to prevent any inadvertent triggering of the interpreter by random combinations of data.
