Hi,

I would like to control my Sacrtrac Rotor by Skyroof.
For that I have to to start rotctld.exe -m 202 -r COM6 -s 9600 -T 127.0.0.1 -t 4533 and got an error "Invalid configuration"
:
rot_init called
initrots4_easycomm called
rot_register (201)
rot_register (202)
rot_register (204)
set_conf: called
rot_open called
serial_open: COM6
serial_setup: tcgetattr
serial_setup: cfsetispeed=9600,0x000d
serial_setup: cfsetospeed=9600,0x000d
serial_setup: data_bits=8
serial_setup: parity=0
serial_setup: Handshake=None
serial_setup: tcsetattr TCSANOW
serial_setup: tcsetattr failed: No error
Invalid configuration

When I omit "-s 9600" in the syntax, I'll get no error, but it seems that there will be no communication between rotctld and SkyRoof...

COM6 is the USB2Serial Controller (USB-Serial CH340) for the Sactrac-Rotor.
By using Putty I can control the Rotor. The Rotoc-Controller shouls work with Hamlib and
The Rotor-Controller should work with Hamlib EasycommII Model.

Portsettings for COM6:
Bits per second: 9600 (should be for Sarctrac)
Data bits: 8
Paryty: none
Stop Bits: 1
Flow control: none

Fifo Buffers are on
SerEnum is not enabled (default)
ModemHandShake is not disabled (default)

Any idea about the problem?

Greets
