This looks exactly like the problem I reported in this news group some weeks
ago (466@gufalet.UUCP).
In my case, when set at 19200 baud by Systems and Devices, our uucico
(HP-UX 2.10) wouldn't use this speed when opening the RS232 port, and the
speed defaulted to 300 baud. Flow control prevented loss of data, but in
Grant's case there seem to be flow control problems (the Trailblazer pumping
19200 bps in a 300 bps port without flow control...)
Hewlett-Packard said it might be a 'feature' of the HDB uucico. 
Anyway, after updating our system to HP-UX rev 3.10 the problem disappeared.

OOPS! Not true! I have not yet figured this out, but it is not OK yet!
