Hi,
I have used simular converters before and this sound like a driver issue. I
found that the USB-Serial converters from EasySync is the best and when
connected to Linux provides a full 'real' serial port without any issues.
Simply connect to ttyUSBx and continue from there.
Are you able to communicate using Minicom for example?
Regards,
W
