MFJ-1278B MULTI-MODE

OPERATIONAL COMMANDS

CANPAC n

Mode: Packet

Default: $19

Parameters:

n0 - $7F, specifying an ASCII character string code.

CANPAC is used to change the cancel-packet input editing command character. The parameter n is the ASCII code for the character you want to type in order to cancel an input packet. You can enter the code in either hex or decimal.

If you cancel a packet in Converse Mode, the line will be terminated with a <BACKSLASH> character and a new line. You can only cancel the packet that is currently being entered. Once you have typed the send-packet character, or waited PACTIME (if CPACTIME enabled), the packet can not be canceled even if it has not been transmitted.

Packet cancellation, like other input editing features, is disabled in Transparent Mode.

Cancel Display Output

The cancel-packet character also functions to cancel display output in Command Mode. If you are in Command Mode and type the cancel-packet character, any characters that would be typed on the screen (except echoed characters) are "thrown away" by the MFJ-1278B. Typing the cancel-output character a second time restores normal output. To see how this works, try typing DISPLAY, then type a <CTRL-Y>. The command list display will stop. You won't see any response from the MFJ-1278B to commands. Now type another <CTRL- Y>, and type DISPLAY again to see that the display is back to normal.

You can use the cancel-display feature if you inadvertently do something that causes the MFJ-1278B to generate large amounts of output to the terminal, such as giving the DISPLAY command or setting TRACE ON. If you are in Converse Mode or Transparent Mode and want to cancel display output, you must exit to Command Mode and then type the cancel- packet character.

The default character for the CANPAC command is a <CTRL-Y>.
