Mcon - Advanced Electronic Applications PK-88 Operating Manual

PK-88 OPERATING MANUAL
NOTE: When using the MBX feature, your station is not part of the protocol handshake be-
tween the originating and receiving stations. If noise bursts or interfering packets
collide with the data being transferred between the two distant stations, you may
miss one or more packets and lose one or more lines of text.
Use the MBX feature when channel conditions are at their best and the source station originating
the transmissions is strong.
⇒ An inbound connection deactivates the MBX command.

Parameters:
Use MCON for selective monitoring of other traffic while connected to a distant station.
MCON works in similar fashion to MONITOR, but affects your display while in the connected state.
As the value of MCON settings is increased, additional functions are included in the monitoring se-
quences.
Frames meant for you are displayed as though monitoring was OFF. You will see only the data.
When MCON is set to '6,' frames meant for you are displayed as any other monitored frame. The
headers appear together with the data.
The meanings of the parameter values are:
0 Monitoring while connected is disabled.
1 Only unnumbered (UI) frames resulting from an unconnected transmission are displayed.
Use this for an 'unproto,' roundtable type contacts. Other mutually connected stations using
the frequency are also displayed. This setting also display beacons.
2 Numbered (1) frames are also displayed. I-frames are numbered in order of generation and
result from a connected transmission. Use this to monitor connected conversations in prog-
ress.
3 Connect request (SABM or 'C') frames and disconnect (DISC or 'D') frames are also dis-
played with the headers.
4 Unnumbered acknowledgment (UA) of connect- and disconnect-state frames are also dis-
played with either the characters 'UA' or 'DM' and a header.
5 Receive Ready (RR), Receive Not Ready (RNR), Reject (RJ), Frame Reject (FRMR) and
(I)-Frames are also displayed.
6 Poll/Final bit and sequence numbers are also displayed.
Monitored frame protocols are shown by the type of brackets:
< > indicates AX.25 Level 2 Version 1 frames
[ ] indicates AX.25 Level 2 Version 2 command frames
( ) indicates AX.25 Level 2 Version 2 response frames
