  • What? No IO::Socket?!?
    • Hey, that's taking the easy way out. IO::Socket is just a convenience wrapper around the raw socket routines.

      • So whats wrong with opening /dev/tcp and using some judicious ioctl on it then ;-}

        /J\
        • /dev/tcp! The luxury! Why, in my day, we had to compose Ethernet frames by hand and fiddle with network card I/O ports to get anything sent. And there weren't none of this full duplex nonsense back then, either. You young whippersnappers....

            I once wrote code to transmit 16 data streams in parallel using a parallel IO port which had each of the 16 bits connected to a different channel. The parallel port had to be written at the right times to generate the start and end of each bit. The bit stream for each port had to be modified to ensure that there were never more than 4 consecutive bits the same. Clock times for the processor were measured in Khz.

            This code was used to send updates to traffic light controllers. I don't know if they are still using that code (that was 20 years ago).
