MFJ-1278B MULTI-MODE BASIC OPERATION
Monitoring on the Air
This is a good time to try out the MFJ-1278B's monitor functions. While you and your friend
are separately connected, type
<CTRL-C>
cmd: MONITOR ON
cmd: MCON ON
cmd: CONVERS
You will be able to see both your "conversation" and your friend's conversation. Also try
HEADERLN ON and MHEARD.
Special Input Characters
The MFJ-1278B has a number of special characters that can be used to control its actions.
Many of these special characters can be used to "edit" commands and packet text as they are
entered. These features can all be customized to suit you and your computer. Most of the
special input characters we will describe are active in both Command Mode and Converse
Mode; the exceptions will be noted.
The character used to return to Command Mode from Converse Mode is by default a
<CTRL-C>. (Sending a BREAK signal also works.) This character does nothing in
Command Mode, so if you accidentally enter it twice you will not mess up the next command
line. You can change the Command Mode entry character with the command COMMAND.
This is one of several commands that set special character functions. You can choose any
character for this function, by entering the ASCII character code for the key. For example,
you can use a <CTRL-E> to enter Command Mode by setting
cmd: COMMAND 5
was $03
The MFJ-1278B displays the previous value in hex, and you can also enter character codes in
hex if you prefer. All of the special characters described below can be changed in the same
way as COMMAND.
We have already mentioned that you can erase mis-typed characters by typing the
<BACKSPACE> character. You can change this character with the command DELETE. If
you set DELETE ON, you can erase characters by typing the <DELETE> character; setting
DELETE OFF returns to using <BACKSPACE>. You will probably want to use the same
key that your computer normally uses to rub out characters. <BACKSPACE> is more
commonly used than <DELETE> by personal computers.
If you are not sure whether your rubout key produces <DELETE> or <BACKSPACE>
characters, you can try both settings of the
DELETE
command and see which works.
