IOPort is a MEX file for precise control of input/output hardware, e.g.,
Serial ports (or emulated serial ports like Serial-over-USB etc.),
parallel ports, network ports, and special digital I/O boxes.

Goal: ___________________________________________________________________

It provides a unified cross-platform interface to such devices and tries
to bundle functionality in one MEX file that is common to all those
devices, but implemented differently on each of them. An example would be
sending of trigger signals: The step to send a trigger signal is always
the same. Your code wants to send a trigger signal immediately (with
lowest possible delay), at a scheduled point in time, or automatically in
response to some event like stimulus onset. However, the mechanism to
send triggers is different for different devices. IOPort tries to provide
a unified interface for such cases, so you need to code only once and
IOPort takes care of the nitty gritty differences between different
devices in how they send trigger signals.

So far the theory. The current implementation of IOPort only provides
unified support for accessing the serial ports of your computer. All
other functions and device classes will be added in future releases of
the driver.

Usage: __________________________________________________________________

IOPort has many functions; type "IOPort" for a list:
IOPort

For explanation of any particular IOPort function, just add a question
mark "?". E.g. for 'OpenSerialPort', try either of these equivalent forms:
IOPort('OpenSerialPort?')
IOPort OpenSerialPort?
