ardop: support version 2

cbs228 opened this issue · comments

Specifications for ARDOP version 2 were released 15 May 2018. This new version breaks both RF and TNC compatibility with ARDOP version 1. Since then, "beta" implementations of ARDOP 2 have been released for Windows and Linux. Version 1 is still around, and at least some RMS nodes continue to operate it. But it is likely that version 2 is the future. We should update wl2k-go to support the new TNC.

An initial reading of the new TNC specification indicates that the following commands have changed:

  • DIRTYDISCONNECT → ABORT
  • ARQBW arguments
  • CONNECT → ARQCALL
  • ARQTIMEOUT
  • BUSYLOCK → BUSYBLOCK
  • BUSYDET
  • ENABLEPINGACK
  • FECMODE arguments
  • MONITOR
  • NEGOTIATEBW
  • PING
  • OVER removed
  • PING
  • PURGEBUFFER
  • A variety of RADIO commands were added
  • RESTOREBUFFER
  • SENDCQ
  • TUNERANGE

The following responses have changed:

  • CANCELPENDING
  • CONNECTED arguments
  • CQ
  • RADIOFREQUENCY → FREQUENCY
  • NEWSTATE arguments
  • PENDING
  • PING
  • PINGACK
  • PTT new behavior
  • REJECTED...

And probably others. The TNC interface is almost completely different. In addition, CRCs are not used on TCP/IP. (If they ever were.)
