Setup TNC to transmit with squelch open???

Setup TNC to transmit with squelch open???

AF8F 26 Jan 2013 20:12

I have a Timewave PK-96 TNC. APRSIS32 will only transmit when the squelch is not open. Does anyone know which TNC command will enable transmit with an open squelch? Transmit should only be restricted when a data carrier is detected.

Thanks for your help.

Found it:

DCdconn ON|OFF Default: OFF

OFF RS-232 cable Pin 8 is permanently set high (default).
ON RS-232 cable Pin 8 follows the state of the CON (or DCD) LED.

DCDCONN defines how the DCD (Data Carrier Detect) signal affects pin 8 in the RS-232 interface to
your computer or terminal. Some programs such as PBBS software require that DCDCONN be ON.
DCDCONN also works in the RAWHDLC and KISS modes. In RAWHDLC and KISS, no packet connections
are known to the PK-96. With DCDCONN ON, the state of the radio DCD is sent to the RS-232
DCD pin (pin-8). This may be necessary to some Host applications that need to know when the radio
channel is busy.
