   i use imp245 (of irv hoff fame) and at 2400 baud it loses the third char
of every line on my II/83.
 
   i imagine this is due to the screen handling routines in ROM, as it
apparently takes more time to handle a carriage return than it does to
put a char on the screen.
 
   the best solution would be to use a lower baud rate until you can either
increase the processor speed or install a rom that handles the screen
quicker.  at 2400 baud, i have no problems when i configure the host system
to insert 3 nulls after every carriage return.  at 9600 baud you'd probably
need 40 or 50 of them.
