Mode: Morse/Baudot/AMTOR
LOCK
is an immediate command that instructs the PK-232 to measure the speed of received Morse
code signals and lock its timing to the speed of the incoming signals.

LOCK
The
command may improve the PK-232's ability to decode CW signals in the presence of
high noise levels.

link at any one time.

If some, but not all, of the outstanding packets are acknowledged, a smaller number may be
transmitted the next time, or new frames may be included in the retransmission, so that the total
number of unacknowledged packet frames does not exceed

When the amount of traffic, the path in use, the digipeaters involved – or other variables not
under your control – make Packet operation difficult (as shown by lots of retries!), you can actually
improve your throughput by reducing
If packet traffic is heavy or the path is poor, reduce
If you're sharing the channel with several PBBSs and digipeaters or when working a PBBSs or
other types of host computers, reduce
If the radio link is good, an optimal relationship exists between the parameter set by these
commands, so that the maximum number of characters outstanding doesn't exceed the receive
buffer space of the TNC receiving the data.

MBX
The
command permits you to read or record useful or needed data without having to connect
or log on to the source station(s). Channel occupancy and bandwidth are conserved on busy chan-
nels.
MBX
filters the received packet data so that only packets from the selected station(s) are shown,
without headers, codes or repeated frames.
The
MBX
command overrides normal monitor functions and can show one or both sides of a con-
versation. You can enter a single call sign, or two call signs, separated by a comma:
