Test program that demonstrates the problem

Testing revealed that Starcraft sets ReadIntervalTimeout to 5 and all other
COMMTIMEOUTS members to 0. The problem, as demonstrated by the attached test
program, appears to be that Wine ignores ReadIntervalTimeout if the read is
asynchronous and so the read operation never times out.

I've tried editing server/serial.c to take the interval timeout into account,
but nothing I can think of is very elegant. Help from other developers would
really be appreciated.
