Cabling:
  Basically, there are two kinds of serial ports,
    DCE (Data Communication Equipment), normally Modem, printer, or serial device.
    DTE (Data Terminal Equipment), normally dumb terminals.
  Connecting a DCE device to a DTE device you can use a regular straight-through cable
  Connecting the same types together, you must use a null-modem cable.
