To all Heath H-89 users:

	I have an H-89 running CP/M 2.2.03 which I am attempting to
interface(RS-232 serial) with an Okidata Microline 92 printer. Everything
seems to work except I can't use the printer at a speed higher
than 1200 baud. Both CP/M and the printer can be configured
for up to 9600 baud, but there appears to be a handshaking problem
which , when I try to print a long listing (longer than 2k bytes,
the size of the printer buffer) I lose much of the data.
The printer can be configured for many protocols, but no one
seems to know the correct one.

	I would very much like to resolve this problem (obviously).
Please respond if you have some helpful info.
