PK-232 – MBX OPERATING MANUAL COMMAND SUMMARY
4/91 A-50 175
The MARSDISP command permits the Baudot and AMTOR operator to detect and display every
character including LTRS and FIGS sent by the other station. The ACRDISP and ALFDISP may be
turned off to prevent extraneous carriage-returns and Linefeeds from being sent to the display. If
this data is retransmitted, ACRRTTY should be 0, and ALFRTTY should be OFF. The <CTRL-O> and
<CTRL-N> characters will send LTRS and FIGS respectively.
MAXframe "n" Default: 4
Mode: Packet Host: MX
Parameters: "n" - 1 to 7 signifies a number of packet frames.
MAXFRAME limits the number of unacknowledged packets your PK-232 permits on the radio link,
and the number of contiguous packets your PK-232 will send in a single transmission.
The "best" value of MAXFRAME depends on your local channel conditions. In most cases of local
keyboard operation, the default value of MAXFRAME 4 works well. When the amount of traffic is
heavy, the path in use is poor or you are using many digipeaters, you can actually improve your
throughput by reducing MAXFRAME. Use MAXFRAME 1 for best results on HF Packet.
MBEll ON|OFF Default: OFF
Mode: Packet Host: ME
Parameters: ON - Will send 3 BELL characters to the terminal when the callsign(s) of the sta-
tion(s) monitored match the MFROM and MTO lists.
OFF - As is, that is the PK-232 will not send any BELL characters to the terminal
due to MONITORED packets.
MBELL can be used to alert the user to the presence of particular packet station(s) on the fre-
quency. For example if you want to be alerted when N7ML comes on frequency you would set the
following:
MBELL ON MONITOR 4 MFROM yes N7ML MTO NONE
When MBELL is ON, packets from and to all stations are displayed, but only those packets match-
ing the MFROM and MTO lists cause the bell to ring.
MBx call1[,call2][-"n"][ALL] Default: none
Mode: Packet Host: MB
Parameters: call - The call signs of one or two stations to be monitored.
"n" - 0 to 15, indicating an optional SSID.
The MBX command permits you to read or record useful or needed data without having to connect
or log on to the source station(s). MBX filters the received packet data so that only packets from
the selected station(s) are shown, without headers or repeated frames. MBX overrides normal
monitor functions and can show one or both sides of a conversation.
The operation of MBX command is as follows:
MBX NONE (Default) All monitored frames are shown with their headers.
