This command is used to change the cancel-line input editing command character.
When in Convers or Command Mode entering a <Ctrl+X> will cancel all characters input
from the keyboard back to the last un-PASSed carriage return (unless PACTIME has
expired, CPACTIME is turned on, and you are in Convers Mode).

CANPAC n
default $19 <Ctrl+Y>
This command is used to change the cancel-packet command character. When in the
Convers Mode entering a <Ctrl+Y> will cancel all keyboard input back to the last
unpassed SENDPAC character (unless PACTIME has expired and CPACTIME is
turned on).
This character also functions as a cancel-output character in Command Mode. Typing
the cancel-output character a second time re-enables normal output. For example, if
you've told the TNC to do a DISPLAY, a <Ctrl+Y> will cancel the display and a second
one re-enables the cmd: prompt after the next ―CR‖.

CD {INTERNAL | EXTERNAL | SOFTWARE}
default INTERNAL
The CD command selects which carrier detect method will be used.
When set to INTERNAL, the TNC will detect a signal present on the channel, using an
energy type carrier detect, allowing shared voice and data on the same channel.
When set to EXTERNAL, the carrier detect is supplied by an external device, connected
to the XCD pin on the radio port.
If set to SOFTWARE, the firmware inside the TNC will detect the presence of data to
enable the carrier detection, allowing operation with un-squelched audio. Correct
operation of SOFTWARE carrier detect is affected by proper equalization and the SWP
parameter. If your RCV light flickers, this is an indication that you may need to adjust
the equalization. (Equalization is set with an internal jumper.)
When CD is set to INTERNAL or SOFTWARE, the external carrier detect pin on the
radio connector (if wired) is used to hold off the TNC from keying the radio.
Hint: For one use of this function, see the APRS and GPS section of this manual.
