KPC-2400
Packet
When ON, the Bell 202 tones received at the TNC input from the transceiver audio output circuits
are equalized for improved performance of the demodulator. Transceiver audio circuits vary in the
amount of "roll-off" of higher frequencies. Test your station with the EQUALIZE ON and OFF to de-
termine which setting is best. Indication of the best setting is generally the one which results in
fewer retries when sending packets. This command has no effect on 2400 b/s operation.
EScape
ON | OFF
default OFF
All Units
Packet
This command specifies the character which will be output to the terminal when an escape charac-
ter ($1B) is received in a packet. When OFF, $1B is sent, this is useful if your terminal interprets
ESC characters as screen positioning commands (ANSI). When ON, the escape character is sent as
a dollar sign ($).
EXtmodem
ON | OFF
default OFF
KAM
/
KPC-4
Packet
When ON, the optional external modem (KM-2400 or MSK Modem) is used on the VHF radio port
(Port 2 for KPC-4).
Fec
[xxxx[xxx]] characters (or 4, 5 or 9 digits)
immediate
KAM
AMTOR
This command sets the TNC in FEC Mode. When a selcal is specified, xxxxx[xxx], the TNC will call
the specified station using SELFEC (Selective FEC).

Packet/RTTY/ASCII
When ON, this command will inhibit the printing of control characters ($00 – $19) which may be
present in monitored packets. This will be useful if you are monitoring channel traffic which in-
cludes binary file transfers or higher level protocols (networks talking to each other). Control char-
acters which may be embedded in those packets can have strange and unpredictable effects on
the monitoring TNC. All control characters except carriage return ($0D) and line feed ($0A) will be
filtered. This command DOES NOT affect receipt of control characters in packets received from a
"connected" station when MONITOR is OFF.
This command also inhibits the printing of control characters in the ASCII Mode (
KAM
).
