Re: [Hamlib-developer] hamlib 1.2.8 and IC-7400

Hi Lada,

just tested a bit with minicom. Echoing seems to work, if 7400 is
turned on then the output on startup is (modem initialization):

If I start with 7400 turned off then:

And I tried 'lsof /dev/ttyS0' as well. If rigctl is not started, no
program accesses ttyS0. If rigctl is started, then only rigctl is
listed.

# lsof /dev/ttyS0
COMMAND  PID  USER   FD   TYPE DEVICE SIZE NODE NAME
rigctl  3470 df6fr    3u   CHR   4,64       800 /dev/ttyS0

I didn't test the signal shapes yet, but I am sure now, that the
hardware is alright. Any other suggestions why it works with N1MM and
not with hamlib? Did I get all the parameters right?

$ rigctl --model=346 --rig-file=/dev/ttyS0 --serial-speed=19200
--civaddr=0x66
--set-conf=data_bits=8,stop_bits=1,serial_parity=None,rts_state=ON,
dtr_state=ON -vvvvv

tks agn es 73,
Corny
