[Hamlib-developer] failures with latest kenwood.c in CVS

[Joop S. <pa...@de...>]

Hello hamlib lovers,

Just a quick report with the latest hamlib CVS. I noticed
changes to the kenwood_transaction function, which causes failures
with xlog. The first few commands are OK, then a get rejects and
timeouts. Xlog polls the rig every 350 ms for information on
frequency, mode, ptt and s-meter (darn, wanted to test and commit
get_level(RFPOWER) for those extra xlog fields). 

Failure starts with a reply to the second 'IF;' command 
(used for get_ptt). Here is the trace, starting from the beginning:

[...]

As you can see, response from the rig is incomplete in 2 out of 4 commands.
Maybe Stephane says "AHA!" here, but I sure don't, at least not after
I have studied the code more thorougly.

I will be happy to do more tests.
