Hi Tony
 At 1200 Baud? I've never seen this happen in the past.
I've run emulations at 19.2K without dropping characters
with the code I have ( I have a special line feed routine
to the screen that scrolls one line at a time to keep
from missing any input ). In anycase, this is in the
middle of a line. It may be that I am not looking at
the info from the UART correctly on the IMSAI end.
I would suspect that over a problem on the PC end.
It is a AMI part ( can't recall the number ) that
is pin compatable with an AY-5-1013. I don't have
full specs, only pinout, but could it be possible that
 the CPM code is beating the TBE signal after I send a
character? Maybe I should add a code loop to wait for the
TBE to go low after each write to the UART? Or maybe,
I'm not even testing the correct bit?
What do you guys think?
Dwight
