    Okay, but to avoid any confusion what do you define as
"wait-for-something"? In my particular implementation the call to
"dosread" 
was only made if at least a single character was waiting. The 
dosread(buf,4000,return) took considerably longer than
dosread(buf,num_waiting,return). If this is due to my not having the port open 
in "wait-for-something" mode, then how do you define that so I can correct 
that oversight.
