Thanks,
Found a solution: I had to run "stty -F /dev/ttyS0" in the host. The configuration is: the host hardware port (/dev/ttyS0) in this case is connected to the guest serial port (/dev/ttyS4) via ssl4=tty:/dev/ttyS0
My guess is that doing "stty -F /dev/ttyS4" in the guest does not pass through the uml - host channel and therefore doesn't set the host serial port (/dev/tttyS0). Probably something desirable and more secure.

Does reducing the MTU of the UML eth0 device help?
