Software TNC Emulator TFKISS is based on TheFirmware by NORD<LINK, license policy given by 'copyrght.txt' in this archive. ALAS is a german license for ham radio software. Most everything of the AXIP-interface is taken from AX25IP written by Mike Westerhof KA9WSB.The PID change code was written together with Joachim, DL8HBS. The FLEXNET decoding code was written by Rene, DG0FT. The other code and all adaptions are written by me. I put this code under license policy of ALAS, too.DescriptionTNT, my hostmode terminal program needs a TNC with TheFirmware connected on a serial interface. There are some applications, where other configurations are needed:- The TNC or PR-controller software is not compatible to TheFirmware and its hostmode, but does support KISS mode- The interface is not on a HF-frequency, but a TCP/IP-based network (local net or internet)- TNT together with DPBox shall be used directly connected to a digipeater using KISS mode (hopefully with CRC) as interfaceTo handle these applications, TFKISS was written. It is in fact a porting of the original TheFirmware by NORD<LINK, written for TNC2-hardware. The low level interfaces were changed and adapted to Linux. On the radio side a KISS- and an AXIP-interface take the place of the HDLC/modem interface. The host connection is changed to a direct console interface (for terminal mode) and a socket interface (for TNT).
