I was expecting this to be the case.

4.3 BSD uucp has a couple of alternatives to the normal "g" protocol
which may be worth trying. The "f" protocol is intended for use over
an X.25 network and may be better able to deal with delays.  The "t"
protocol is intended to let you run uucp over a TCP network.  We use
it here as a kludge for transferring news and it runs really fast. It
would be interesting to find out if either of these protocols worked
better with the Telebit.

I've seen the CDS V.32 full duplex 9600 over dialup modems but they
are about $3500. Also, they are sync only, although you can get
converters I assume.
