Hi Guys... i hope someone can help me out here.
In the serialPortSample.h on line 517 in the InitializeModem();
function there is this classic "read" command. But when no modem is
here or the cable is unplugged, it hangs there for an infinite amount
on time.
My question is rather simple:
Is there a way to find out if the cable is connected or the other
way... to define a timeout, that it will return with an error?
Thanks
Boris
