A new (hopefully) iteration with Magellan eXplorist tools – an automation objects to script GPS data processing. The idea is to provide scriptable objects to access GPS data for various tasks from just logging into file to [the target is believable to be] publishing geolocation information in real time through Jabber/XMPP server in conformance with XEP-0080: User Geolocation.
Currently, it is a lower layer serial connection object to GPS communication port, AlaxInfo.MagExpToo.SerialConnection.
The script below prints GPS NMEA-0183 output to console:

Copy paste sample code into 01.js file:
function SerialConnection_Error(Code)
{
WScript.Echo("Error: " + Code.toString());
}
function SerialConnection_Input(Lines)
{
LineArray = (new VBArray(Lines)).toArray();
for(Index = 0; Index < LineArray.length; Index++) WScript.Echo("Input: " + LineArray[Index]); }
SerialConnection = WScript.CreateObject("AlaxInfo.MagExpToo.SerialConnection");
WScript.Echo("Assumed Port: " + SerialConnection.AssumedPort);
SerialConnection.Port = SerialConnection.AssumedPort;
WScript.ConnectObject(SerialConnection, "SerialConnection_");
try
{
SerialConnection.Connect();
while(true)
{
WScript.Sleep(1000);
// NOTE: Dead loop
}
}
catch(Error)
{
WScript.DisconnectObject(SerialConnection);
throw Error;
}
WScript.DisconnectObject(SerialConnection);
There will be more to interpret certain NMEA sequences, in particular the ones that refer to fixed position.
