4.4.5.4 The MFILTER Command
Some terminals and computer programs are sensitive to certain
characters that may appear 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-900 default for MFILTER is $80 which prevents most control
characters from interfering with your display. If you find a terminal
or printer is bothered by certain characters, 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-900 on and enter your callsign, anyone can
Connect to you. If you are at your terminal or computer when this
occurs you will see the LCD for the appropriate channel showing
the word CONNECTED.
When a packet connection occurs, the PK-900 automatically switches
to the Converse mode so what you type on the keyboard will be sent to
the connected station. The NEWMODE and NOMODE commands control when
and how the PK-900 changes to and from Command mode in response to
packet connects and disconnects. You will probably never need to
change these settings.
4.4.6.1 Time-Stamping Connects
Sometimes it is useful to know what time someone connected to you -
perhaps for logging. To time-stamp your connects and disconnects turn
the command CONSTAMP ON. As discussed in the Monitoring section
above, turning the command DAYSTAMP ON adds the date to this as well.
The DAYTIME command must first be set for this to operate.
4.4.6.2 Connect Alarm
If you busy doing other things, you may want to be alerted when
someone connects to you. Turning the command CBELL ON rings the bell
on your terminal when a station connects to, or disconnects from you.
