function y = SerialComm(op, port, data)
% SerialComm -- Serial port interface for OSX
%
% CAUTION: SerialComm() is deprecated! Not supported on Linux, Windows or
% 64-Bit versions of Psychtoolbox for OSX, totally unsupported by us. Use
% IOPort() instead as a future-proof, much more capable cross-platform
% solution.
%
% SerialComm( 'open', PORT, CONFIG ) opens comm port number PORT for reading and
% writing. The CONFIG string specifies the basic serial port (baud rate,
% parity, #data bits, #stop bits) in standard DOS format. CONFIG defaults
% to '19200,n,8,1'.
%
% STR = SerialComm( 'readl', PORT, EOL ) reads one line of ASCII text from PORT
% and returns the line in the string array STR. If a complete line is
% not available, STR is empty. If supplied, EOL defines the End-of-Line
% character which remains in effect until changed. On open, the EOL
% character is the ASCII line-feed (0xA). Non-blocking.
%
% DATA = SerialComm( 'read', PORT, N ) reads upto N bytes from PORT and returns
% the uint8 array in DATA. If no data is available, DATA is empty. If N is
% not specified, all available bytes are returned. Non-blocking.
%
% PORT = SerialComm( 'name2number', PORTNAME) converts a port in string
% form, eg. /dev/cu.KeySerial1, to an actual port number for use in the
% other functinos.
%
% SerialComm( 'write', PORT, DATA ) writes contents of the matrix DATA to PORT.
% The matrix DATA can be of class "double" or "char".
%
% SerialComm( 'purge', PORT ) purges read and write buffers for the PORT.
%
% SerialComm( 'hshake', PORT, HSHAKE ) set hardware 'h' and/or software 's' hand-
% shaking. 'n' sets handshaking to none.
%
% SerialComm( 'break', PORT ) sends a break.
%
% SerialComm( 'close', PORT ) closes the PORT.
%
% SerialComm( 'status', PORT ) prints some status info.
