Making SLOTTIME smaller will cause the TNC to generate the random number
more frequently, whereas raising the PERSIST value will give a better chance
(improve the odds) of transmitting the data. Through careful choice of these val-
ues, it is possible to improve data throughput while at the same time permitting
shared channel usage by other packet stations (where all stations use a similar
value). The persistence algorithm has been added on top of the DWAIT algo-
rithm.

PHEARD [CLEAR]
immediate
This command will display a list of the last 10 stations that have connected to
your TNC PBBS. The list will show the callsign of the connecting station and the
last time they connected and disconnected.
To clear the PHEARD list of all current entries, enter PHEARD CLEAR.

PID {ON | OFF}
Multi-Port
default OFF/OFF
When OFF only those packets with a protocol ID of $F0 (pure AX.25) are dis-
played. When ON all packets are displayed. Some of the information in
non-AX.25 packets (for example: TCP/IP, NET/ROM or TheNet) can cause some
computers to lock up. Net/Rom, TheNet and G8BPQ nodes have a PID of $CF,
TCP/IP uses $CC and $CD, and standard AX.25 is $F0.
+ If you wish to monitor with PID ON, you also may want to set the FILTER pa-
rameter ON. This will prevent monitored data that may look like control charac-
ters from being sent to your terminal.
