I had a similar problem when I tried writing an inefficient terminal
program in BASIC.  Apparently, it didn't read the characters as fast
as they came in, and the interface buffer became overloaded.
Remember, this was BASIC, but I was only running at 300 baud, so
unless you have some rather efficient ML code, problems like
this are to be expected.  I would look for a different terminal
program, one which advertises that it can be used with 1200 baud,
or else write something myself which sends an X-OFF signal
after every few characters, giving the 64 some time to "digest"
the data, and then sends an X-ON, telling the host to continue
where it left off.
