I had problems when I went to 19,200 baud, so I wrote an insert for 
Ybbat, the Fidonet mailer, which buffers in characters into an internal 
queue.  I can then take characters off the que.  You could also use an 
interrupt driven system.  I have a Kaypro, so I doubt my code would do 
you much good unless your TRS has a Z80 SIO for serial IO.  If so, the 
file is called YBH-KAY1.ASM, and it is on C1: on my system, The Black 
Box, 713-480-2686, 300-19200 baud.
