[Hamlib-developer] hamlib 1.2.8 and IC-7400

[Corny, D. <df...@gm...>]

Hi,

a few weeks ago I got my new radio, a IC-7400, and I thought it would
be useful for contests to connect it to a laptop via CIV. So I built
the opto-isolated converter: http://www.plicht.de/ekki/civ/if-gary.html

Since I want to use N1MM as contest logger, I first tested it on
RedmondOS with N1MM and it worked out of the box. So I thought it
should be no problem to run it with hamlib for my everyday logging on
Debian Lenny. I installed lihamlib2 and libhamlib-utils, version
1.2.7..., but I had some problems. So I installed 1.2.8 from source.

I adjusted the rigctl parameters to the values N1MM uses, but it does
not work as expected. Here is my command used:
$ rigctl --model=346 --rig-file=/dev/ttyS0 --serial-speed=9600
--civaddr=0x66 --set-conf=data_bits=8,stop_bits=1,serial_parity=None,
rts_state=ON,dtr_state=ON -vvvvv

The thing is, hamlib only receives rubbish, but can send commands to
the IC-7400 which are executed, i.e. setting frequency and mode. If I
want to get the frequency with f: "get_freq: error = Communication bus
collision".

Here is a complete copy of the trace, including successful set commands:

I would be very glad if someone could point me in the right direction,
where I should take a closer look at. I am not a subscriber to the list,
so please put me in the Cc.

Thanks a lot and 73,
