Hello

I have this piece of code to read from a serial port

sysread(COM,$buf,1);
unpack("C*",$buf);

[download]

but it seems to never time out if there is nothing to read. Is there a non-blocking system equivalent (that's to say, not using the SerialPort module) to the above code - one where I can control the timeout value?
