Hi Peter
:Then I wrote KISS support. And here I got a big problem. I made a loopback
:on the TNC (SIO out + SIO in) and with JNOS everything works.
Guess you mean a direct wiring on the radio side.
:And both frames were received only in such case:
:- first frame is transmitted to TNC
:- TNC transmits it to trx
:- <PTT goes off>
:- and THEN second frame is transmitted to the TNC
With this description it is quite clear to me what the problem is.
The TNC must be set up for "full duplex" else it won't listen to the radio
port as it sends data. There is probably some buffering that allows your
small packet to be stored but then it's filled up and what you get is
what remained in there.
Probably you will have to set the TNC to that mode before entering KISS mode.
In your info letter following the latest code you complained a bit
about having to do it all yourself, but please take a little rest now
so that we can at least figure out the code you've written.
There is nothing in coding so difficult as reading the code of others :-(
/Anders
