Special character processing

If the Telnet Protocol parameter is set to /Normal, /BCP, or /TBCP, the printer's Telnet server recognizes the following special characters:

Control-T. Server replies with an engine status message.
Control-C. Server transmits abort signal to the interpreter.
Control-D. Server interprets this character as input EOF (End-of-File).

The Telnet protocol defines a number of out-of-band signals. The following table describe the actions taken by the printer's Telnet server upon receipt of these signals.

Signal	Description	Server action
AO	Abort Output	Forces the server to discard all output until the EOF is received. The server continues to forward input data to the interpreter, but all interpreter output is discarded up to and including the output EOF.
AYT	Are You There?	The equivalent of a Control-T; results in an engine status message.
BRK	Break	Silently discarded.
EC	Erase Character	Server discards the last character inserted in the input buffer.
EL	Erase Line	Server discards the last line in the input buffer.
IP	Interrupt Process	The equivalent of a Control-C; the server transmits an abort signal to the Interpreter.
NOP	No Operation	Silently discarded.
