tcflush waits

[Jon Schneider]

I have an app that opens a serial port and sets VTIME to 1, VMIN to 
0.

When it does tcflush(,TCIOFLUSH) or tcflush(,TCIFLUSH) it takes 
exactly 100ms. I don't expect there to be anything to read but this 
call is not supposed to wait.

I tried setting VMIN to something else with no effect.

Windows '98.
cygwin1.dll 1.3.22-dontuse-21

Cheers,

Jon
