[amsat-bb] IC-475H CI-V questions

  I've recently came into an IC-475H that I'd like to use as the uplink
on linear sats.  But I'm having some trouble getting the CAT control to
work.  I'm using grig instead of going in/out of Gpredict just to test
the CI-V link.

I thought that this should work in grig:
grig -m 307 -r /dev/ttyUSB1 -s 1200 -c 14

  but it doesn't seem to connect.  I have visually verified in the 475
the switch settings for the address and speed, they're set to default
$14 1200 baud.  With nothing connected the DC voltage on the remote
output is about 2.0VDC which agrees with the schematic.

  I'm hoping that there is something I've overlooked.  The interface
with grig works with my IC-R7000 
grig -m 340 -r /dev/ttyUSB1 -s 1200 -c 08
