Hummm - if you were _REALLY_ daring, there is a hack that could work.
Or it would help the receiving end.

Set the receiver to say it's window size is seven, and then if transmission
is proceeding normally, only ack each 5th. or 6th. packet. Dirty, ugly, but
in the presence of a true, God fearing, UUCP implementation it would work.
Of course, error recovery and end of file processing would take some doing,
but real UUCP users don't get errors :-)
