Using Kenwood D7 with Linux AX.25

Using Kenwood D7 with Linux AX.25

[John Ackermann N8UR]

I'm trying to use my Kenwood TH-D7A(g) handy-talkie for some packet demos 
and am having real problems.  My basic AX25 configuration is OK as I can 
hook up to a TNC-2 clone with KISS chip and it works fine.

I put the D7 in KISS mode at 9600 baud (which it seems to drop out of on 
every power cycle, grrrr) and hook it up to the known-working linux setup. 
The D7 receives OK but seems to transmit only preamble flags; when you 
listen to a packet, there's just flags with no evidence of a data portion 
and nothing decodes at the other end.  No data comes out of the thing, no 
matter how long I program the TXD.

I understand that the D7 has KISS limitations due to buffer size, but I'm 
not even getting the basic function to work, and that doesn't seem right.

Anyone got a D7 working with kernel AX.25, and have any suggestions for me? 
(As a data point, when the D7 is in normal packet mode using minicom as a 
terminal program it transmits just fine, so the hbaud, etc. are set 
correctly.)

Thanks,

John

John,

last week, I bought the TH-D7E(G) with the new firmware (v. 2).
I succeeded to configure it with mkiss and kissattach (no success with kissattach alone), RX and TX functional on 9k6.
Small problem - it just receives two frames at once, the third one is rejected.
I have still to play a bit with setup of USB-RS232 converter, which I believe, has the problem.
Everything on Mandrake 8.2, kernel 2.4.18, newest libs/tools/apps.

73,

For a short while.... Depends what you're sending. Try some IP... you
might be lucky with a telnet for a bit but after the TCP seq number
rolls around a bit then it will lock up. Try an FTP with plenty of
KISS octets with the top bit set and it will lock much sooner..

Sounds about right..

Look people, just give up on this... IT DONT WORK ! and as
