The port sniffing i have tried, maight not have been exactly like that but i tried with mb2hal and got data in the "sniffer"
When i run the altivar comp i get nothing, its not touching the serialport at all.
i have ran it with -v no difference.
The VFD does have modbus activated since i can read registers with mb2hal component.
That in my world means that serial coms and settings to read the VFD is correct.
Since the VFD comp is changed and compiled against newer linuxcnc software my guess is that something in the modbus lib is wrong and its not able to communicate correctly.

Can you describe sniff method?
I compiled altivar comp on 2.7.0 pre not on 2.8. But I can try it.

Hi
i tried the sniffer you provided
socat -d -d PTY: PTY
halrun:
loadusr -W atv_vfd -g -r 19200 -s 1 -t 1 -v -d /dev/pts/5
setp atv_vfd.spindle-on 1
cat /dev/pts/6
No results at all from cat
if you can try the same on 2.8 it would be very appreciated!

You _must_ set atv_vfd.enable to 1 otherwise nothing at all happens.
here is the source-code
here is the source-code
594 // wait for enable signal after load axis
595 while (!*(haldata->enable)) {
596 // do nothing
597 sleep(1); // be nice to CPU -mah
598 }

i gave in and hooked the VFD up with analog control, maybe someone will get it running in the future.
