NetStation - Basic control of the EGI/NetStation EEG recording system via
TCP/IP network connection. (See http://www.egi.com)

This function was developed and contributed to Psychtoolbox by Gergely Csibra, 2006-2008.
Code is based on Rick Gilmore’s routines, 2005. Thanks!
Code adapted to PCs (and Macs with Intel architecture) by Zhao Fan, 2008.

General syntax

[status, error] = NetStation(‘command’, …)

if status == 0, the command has been succesfully executed
otherwise see string “error” for error message

Commands

NetStation(‘Connect’, host [, port])

       Establishes TCP/IP connection to the [NetStation](NetStation) host computer.  
       "host" is the hostname as a string (e.g., 'anything.com' or '187.14.176.12')  
       "port" is the ethernet port to be used. Default is 55513.  

NetStation(‘Disconnect’)

       Disconnects from [NetStation](NetStation) host.  

NetStation(‘Synchronize’ [, SynchLimit])

       Synchronize to the connected host. "[SynchLimit](SynchLimit)" could specify the maximum allowed difference  
       IN MILLISECONDS. Default is 2.5 ms.  

NetStation(‘StartRecording’)

       Instructs [NetStation](NetStation) to start recording.  

NetStation(‘StopRecording’)

       Instructs [NetStation](NetStation) to stop recording.  

NetStation(‘Event’ [,code] [,starttime] [,duration] [,keycode1] [,keyvalue1] […])
NetStation(‘EventNoAck’ [,code] [,starttime] [,duration] [,keycode1] [,keyvalue1] […])

       Send an event to the [NetStation](NetStation) host. The 'EventNoAck' variant doesn't  
       wait for acknowledgement of reception of the event, whereas the 'Event'  
       version does. Note that the 'EventNoAck' command is included for  
       completeness. It is not a good practice to skip waiting for  
       acknowledgements. If time is an important factor, Event commands can be sent  
       at a later opportunity within a session (e.g., in blocks at the end  
       of experiments).  
  
       "code"      The 4-char event code (e.g., 'STIM')  
                   Default: 'EVEN'  
       "starttime" The time IN SECONDS when the event started. The VBL time  
                   returned by [Screen](Screen)('[Flip](Flip)') can be passed here as a parameter.  
                   Default: current time.  
       "duration"  The duration of the event IN SECONDS.  
                   Default: 0.001.  
       "keycode"   The 4-char code of a key (e.g., 'tria').  
       "keyvalue"  The value of the key (any number or string)  
                   The keycode-keyvalue pairs can be repeated arbitrary times.  

NetStation(‘FlushReadbuffer’);

        Flushes the read buffer.  

Uses a modified version of the TCP/UDP/IP Toolbox 2.0.5, a third party GPL’ed
open source toolbox, which is included in Psychtoolbox,
but also available from the Mathworks website:
http://www.mathworks.com/matlabcentral/fileexchange/loadFile.do?objectId=345

The toolbox has been modified for lower communication latency.
