Hi All,

I am writing an OS/2 device driver (first attempt!) for a realtime
application transmitting data to devices via an RS-232 port, mode
38400,6,n,1. Output is typically 10 to 20 bytes with a required pause
between these 'frames' of 0.6 or 1.2 (the transmission time of 3 or 6
characters), during which the line must be idle (no 'dummy' characters
allowed).  How do I obtain such short intervals reasonably accurate?
Note: The timing is needed in interrupt state of the device driver and the
requesting thread is blocked.
Code samples or references to exiting sources are appreciated!!.
  
Cheers, Rob
