Epson MFJ-1278B manual Delete ON/OFF, Diddle ON/OFF, Mode ASCII/RTTY Default on

MFJ-1278B MULTI-MODE OPERATIONAL COMMANDS

DELETE ON/OFF Mode: Packet Default: OFF

Parameters:

ON The delete character input editing character is <DELETE> ($7F).

OFF The delete character input editing character is <BACKSPACE> ($08).

This command is used to change the input editing command for character deletion. When this character is typed, the last character from the input line is deleted. How the TNC indicates the deletion is controlled by the BKONDEL command.

You can not use this character to delete past the beginning of a line, although you can delete <CR> characters that have been entered in the text with the pass character.

To see a corrected display of the current line after you have deleted characters, type the redisplay-line character, which is set by the REDISPLA command.

DEFLTDLC Mode: Host Default: 254

Parameters:

Effective only when non-0 MYDLCNUM, this parm tells the TNC what the DLC address is of the host (ex, MTHOST). Default is 254.

DIDDLE ON/OFF Mode: ASCII/RTTY Default: ON

During ASCII/RTTY transmit, the MFJ-1278B sends a non-printing synchronization character, DIDDLE, whenever the transmitter is keyed but not sending anything else.

The DIDDLE characters for ASCII and RTTY are NUL and LTRS, respectively.

Diddling while the transmitter is keyed makes it much easier for persons receiving to tune and remain tuned to your transmitted signal.

Some stations running mechanical teletype equipment may ask you not to "Diddle" while you are talking to them since it may cause their older equipment to make a lot of noise, but do nothing. It should be noted that NO damage can occur should mechanical teletypes receive "Diddles", and it is not considered bad practice to leave it ON unless sked otherwise by the other station in the QSO.
