New Features:

• PTT using GPIO pin of CM108/CM119 (e.g. DMK URI, RB-USB RIM), Linux only.

• More efficient error recovery for AX.25 connected mode. Better generation and processing of REJ and SREJ to reduce unnecessary duplicate I frames.

• New configuration option, V20, for listing stations known to not understand AX.25 v2.2. This will speed up connection by going right to SABM and not trying SABME first and failing.

• New application "kissutil" for troubleshooting a KISS TNC or interfacing to an application via files.

• KISS "Set Hardware" command to report transmit queue length.

• TCP KISS can now handle multiple concurrent applications.

• Linux can use serial port for KISS in addition to a pseudo terminal.

• decode_aprs utility can now accept KISS frames and AX.25 frames as series of two digit hexadecimal numbers.

• Full Duplex operation. (Put "FULLDUP ON" in channel section of configuration file.)

• Time slots for beaconing.

• Allow single log file with fixed name rather than starting a new one each day.

Bugs Fixed:

• Possible crash when CDIGIPEAT did not include the optional alias.

• PACLEN configuration item no longer restricts length of received frames.

• Little typographical / spelling errors in messages.

Documentation:

• New document Bluetooth-KISS-TNC.pdf explaining how to use KISS over Bluetooth.

• Updates describing cheap SDR frequency inaccuracy and how to compensate for it.
