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 con-
nected 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 pa-
rameter 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 exam-
ple, 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 $80 (hex) filters all received control characters except <^M>, the
carriage return, <^J>, the line feed, and <^I>, the TAB character.
When entering hexadecimal numbers, be sure to prefix the number with the '$' sign.
Some examples follow:
o
To prevent a <^L> character from clearing your screen, set
MFILTER
to
12
.
o
To eliminate <^Z> characters, which some computers interpret as the "clear
screen" character, set
MFILTER
to
26
.
o
To prevent <^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 ap-
plied 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.
o
Stations heard directly are marked with a
*
.
o
Stations heard through a digipeater are not marked.
