Re: [Hamlib-developer] ROTCTld usb0 issue on pi5

[Randy R. <ran...@gm...>]

I'm trying this on my Pi-Star so I get a different version of Hamlib and 
have a different rotor attached.

It seems to work on mine but I have seen a error like this at one time.

On my Desktop I see what looks like your problem:

/bin/rotctl -vvvvv -m 601 -r /dev/ttyUSB7
rotctl Hamlib 4.6~git 2024-11-09T13:02:04Z SHA=32e6b9 64-bit

gs232a_rot_init called
set_conf: called
rot_open called
serial_open: /dev/ttyS0
serial_setup: tcgetattr

On my system I really have a /dev/ttyS0 so the open works, on your Pi 
you don't.

For a work around:

sudo ln -s /dev/ttyUSB0 /dev/ttyS0

This will create a symbolic link so when rotctl attempts to open 
/dev/ttyS0 it will find one and it will open /dev/ttyUSB0...

Or git a newer version.

Correction:

% ls -l /dev/serial/by-id/
total 0
