The hit would be at the driver level. Data comes in a byte at a time. It will have to make a copy of the the data and act like multiple
serial ports so it can create one stream for each process that wants to read the data. It's the nature of the
serial protocol. As long as it's a standard serial driver you get one process connected per port AFAIK. Multi-tasking or even multi-processors doesn't provide any way to change this.
