OK, we now have fgfs successfully driving the moving map display of gpsdrive.

it's a bit Heath Robinson, but it works.

I have launched ttypatch to link pseudo serial port /dev/ttyp0 to /dev/ttyp1
(the default config for it)

fgfs is writing nmea stuff to /dev/ttyp0 using the following statement:

--nmea=serial,out,5,/dev/ttyp0,4800

I have given up on directly reading the serial port /dev/ttyp1 using gpsdrive, 
so I've enlisted the aid of another program, gpsd, to do the translation 
between them.

gpsd has been launched with

[EMAIL PROTECTED]:~$ gpsd -p /dev/ttyp1

I launched xgps (the test prog that came with gpsd) to confirm that fgfs 
actually was communicating properly... yes.

I then launched gpsdrive and told it to ignore the serial port and to 
communicate with gpsd.

voila... it works... gpsdrive is now functioning as a moving map showing the 
position and heading of the aircraft in fgfs

now time for a good cup of hot chocolate and to put my feet up

tomorrow evening is the time to write this up as a mini Howto for you folks to 
benefit from ;)
