[Hamlib-developer] rotctld south_zero double adjusted?

[Paul <n9g...@gm...>]

Hello,

   I am having an issue trying to get my rotor-ez controller with 
south-centered-meter to work correctly using rotctld to allow a -m 2 
connection. Trace indicates Hamlib 4.6.2 2025-02-09T21:03:50Z. If I 
connect directly with rotctl only, the position reports correctly. Going 
through rotctld, the position is off by 180°.

   Rotator is physically positioned at 180° during below traces.

 >>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>

So, using: *rotctl -m 401 -r /dev/ttyS2 --set-conf=south_zero=1 -vvvvv *

..the position reports correctly and end of trace looks like this:

Rotator command: p
rotctl_parse: input_line: p
rot_get_position called
rotorez_rot_get_position called
rotorez_send_priv_cmd called
write_block(): TX 4 bytes
0000    41 49 31 3b                                         AI1;
read_block_generic called, direct=1
read_block_generic(): RX 4 bytes, direct=1
0000    3b 33 36 30                                         ;360
rotorez_rot_get_position: "360" after conversion = 360.0
rotorez_rot_get_position: azimuth = 0.0 deg; elevation = 0.0 deg
rot_get_position: got az=0.00, el=0.00
rot_get_position: south adj to az=180.00
*Azimuth: 180.00*
Elevation: 0.00

 >>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>

   If I start rotctld like this: *rotctld -m 401 --set-conf=south_zero=1 
-r /dev/ttyS2 -t 4533 -s 4800 -vvvvv*

...and then start rotctl -m 2 -vvvvv, I get this:
