With an rs-232 pack, and earlier versions of nitros9, I felt it was the 
speed that could be obtained from rz/sz that counted most, and that was 
just short of 740 cps.  That compared to 430 cps with normal os9. That was 
with a null modem cable to my amiga, where term, V4.7 had an excellent 
data rate display.

Without the admittedly huge overhead of rz/sz, I expect it could have made 
the full 56k under ideal conditions, but not while writing the file data, 
or reading it to send.  Raw speed for 10 milliseconds isn't exactly a real 
world test IMO.  Neither is zmodem, with its character at a time crc 
calculations, but thats what I was stuck with.
