This part I actually understand.  The OP has a program named
"RouteBuddy" that talks to a device over a serial port, and he
want to repalce the data stream coming from that device.  My
question is, "where does the device that he wants to replace
plug in?"  I don't see anywhere on my laptop I could plug in
anything but a USB connector, an ethernet connector, a firewire
connector, headphones, speakers, a display connector, or a
power cord.
