Most PocketPC's have a serial interface. The one I have looked at has an=20
unbuffered inverted RS232 3.3V port (ready to be connected to a 3.3V MAX2=
32 =20
type driver or directly to a 3.3V PIC). The port isn't mentioned in the=20
standard documentation. The port is normally powerd down but can be power=
ed=20
up via software and/or by jumpering some inputs (used to recognize=20
different type of peripherials). =20

Although the PocketPC has an USB port, most are of slave type, which can'=
t=20
be used to connect to other slave devices, such as printers or USB to RS2=
32=20
converters.
