I read somewhere that cu can only handle about 2400 baud.  One way to
verify it would be to connect a null modem cable between the two
serial ports on your machine and do some timing tests using cu.

I've got one of my serial ports hardwired to a Macintosh. Using my
own terminal program on the Mac I can get about 18K baud zmodem
transfers.

How about using pcomm instead?  It does a nice vt100 emulation
and supports all the popular transfer protocols.
