I had a KP 2x (1984) with the same "feature".  The graphics screen monitor
is so slow that it cannot keep up above 1200 baud.  Microcornucopia sells
a new ROM for Kaypros which is supposed to get you up to about 4800 baud.
The problem is with the line feed portion of the memory mapped I/O.  From
the time that you issue a LF at 9600 baud until the routine returns, you 
have "missed" 3 or 4 characters at the modem port.

A possibility is to modify your modem 7 clone or kermit to issue an XOFF
just before you do a line feed to shut off the incoming characters, do the
LF, and then XON to continue receiving. (Your host will hate you.)

What you really need is an asynchronous modem port handler.  Check with the
local Kaypro gurus and see if there is one.  The problem can't be all that
rare that someone hasn't done something.

Good luck.
