One thing you may want to also try is ppp over this adaptor.  I spent
quite a while trying to get ppp over a utty configured only to find
out that the problems went away when I switched to a real tty/com

    model: DSB-S25 
    umct0: MCT Corporation. USB-232 Interfact Controller, rev 1.00/1.02, addr 4

The symptoms were that the serial-line comms worked just fine, the PPP
LCP packets were full duplex, but none of the IP from the remote side
made it into the IP stack in the kernel.  Tcpdump showed outgoing
packets, but only incoming LCP.  Weird.
