is turned ON, the PK-232 will give a reason why each packet was not displayed. If you
are interested in exactly how the packets are represented, turn on the TRACE com-
mand. See the Command Summary for more information about WHYNOT and TRACE.
4.4.5.2 Monitoring Other Stations While Connected
When you are NOT connected to another station, the MONITOR command discussed
above determines what packets are displayed. When you ARE connected, the MCON
command determines what packets are shown.
The default of MCON is 0 which tells the PK-232 NOT to monitor any packets while you
are connected. Most users like this so they are not disturbed with monitored channel
data when they are communicating with another station. If it is desired to monitor
channel activity while you are connected, then remember to set MCON to an appropri-
ate Monitor number from the list above or the command summary.
4.4.5.3 Selective Monitoring
After you have monitored channel activity for a while, you may decide there are only a
few stations you wish to display. The PK-232 will let you do this with the Monitor-TO
(MTO) and Monitor-FROM (MFROM) commands. With the MBELL command, you can
even be alerted when a certain station transmits on the frequency. These commands
work in conjunction with MONITOR and MCON commands.
4.4.5.4 The MFILTER Command
Some terminals and computer programs are sensitive to certain characters that may ap-
pear in monitored packets. You will know this is happening if occasionally the cursor on
your screen moves to strange places causing the copy to be garbled.
The PK-232 default for MFILTER is $80 which prevents most control characters from in-
terfering with your display. If you find a terminal or printer is bothered by certain char-
acters, see the Command Summary for more information on the MFILTER command.
4.4.5.5 Monitor Without Callsign Headers
Sometimes you may wish to monitor certain stations without wanting to look at the
packet callsign headers. This can be useful when monitoring message traffic from a
large Packet Bulletin Board System (PBBS). The MBX command allows you to choose
the callsign of a station, or a pair of stations you wish to monitor without seeing the
packet headers. See the Command Summary for details.
4.4.5.6 MSTAMP - The Monitor Time-Stamp Command
Monitored packets can be time-stamped if the real-time clock has been set with the
DAYTIME command. To timestamp monitored packets, turn the MSTAMP command ON.
Turning the DAYSTAMP command ON adds the date to the timestamp provided by the
MSTAMP command.
4.4.6 Packet Connects
When you turn your PK-232 on and enter your callsign, anyone can Connect to you. If you
are at your terminal or computer when this occurs you will see a message like the one
