I'm opening /dev/com1 as follows:
fd = open( "/dev/com1", O_RDWR | O_NOCTTY | O_NONBLOCK | O_BINARY );
on NT the O_NONBLOCK works fine.
on win 95, read( fd, buf, max_len ) blocks.
I don't think the termios stuff should affect this, at least if it did, I
should be having the same problem under NT.
Is there a fix for this?
Or, is there any way to check for chars pending before reading?
I'm already using select(), which shouldn't even drop out of the wait until
there's data.
TIA, Bruce.
