PK-88 OPERATING MANUAL
4.9.3
The MCON Command
Use the MCON command for selective monitoring of other traffic on the channel
while connected to a distant station. Use this feature to 'listen' for
specific stations while you are connected to someone else.
Set MCON to 0 or OFF if you do not wish to monitor packet activity when you
are connected to someone.
MCON works like MONITOR but affects your display while connected. As the MCON
setting is increased, more functions are added in monitoring sequences. The
meanings of the parameter values are identical to those shown for the MONITOR
command.
4.9.4
The MFILTER Command
Use the MFILTER command to 'filter' selected characters from packets received.
For example, you can command the PK-88 system to filter out form feeds or bell
characters that may be sent by the station with which you are connected, but
which may interfere with your display or otherwise disturb your operations.
You can specify up to four characters by giving the ASCII character codes in
either hexadecimal or decimal numbers.
The default value of $80 (hex) filters all received control characters except
<CTRL-M>, the carriage return, <CTRL-J>, the line feed, and <CTRL-I>, the TAB
character.
When entering hexadecimal numbers, be sure to prefix the number with the '$'
sign. Some examples follow:
•
To prevent a <CTRL-L,> character from clearing your screen, set MFILTER
to 12.
•
To eliminate <CTRL-Z> characters, which some computers interpret as the
"clear screen" character, set MFILTER to 26.
•
To prevent <CTRL-G> characters from 'beeping' your computer or terminal,
set MFILTER to 7.
Enter the ASCII or hexadecimal values of the selected characters separating
each value with a comma:
cmd:MFILTER $07, $13
4.9.5
The MHEARD Monitor Buffer
Use the MHEARD command to display a list of stations heard since the last time
you applied power to the PK-88, or since the last time the MHEARD buffer was
cleared. Entries in the 'heard' report are also time stamped if the date/time
has been set with the DAYTIME command.
Clear the MHEARD buffer by typing either a 'percent sign' (%), an ampersand
(&), 'N,' 'NO,' 'NONE' or 'OFF' after the command word.
•
Stations heard directly are marked with a '*.'
•
Stations heard through a digipeater are not marked.
