RS-232C or the more robust RS422 are commonly used.
You can also use a minimum IrDA stack with only the IrLAP
protocol if your embedded device has scarce resources.
RS-232C is certainly the easiest if your handheld device
has such a port.

Any experience using handheld external displays to enter/display data
in the field for an embedded device? Whats easist to get up and
running? RS-232 or USB communication ok, wireless less ok. I suppose
options off the top of head are PDA's, palm computers, smart cell
phones, gameboys, or maybe they sell custom
display/keyboard/communication link only units for this purpose?
