UT-41 GPS in OS X

I recently got a UT-41 at http://www.geeks.com/details.asp?invtid=UT-41&cat=GPS
It didn’t support OS X out of the box so here is how I got it working.
First download the Serial to USB driver for OS X at http://www.apple.com/downloads/macosx/drivers/pl2303driver.html. After installing it, you are asked to reboot. Do so.
When you are back to OS X you can download and compile GSPd or get the GUI Binary gpsdXConfig at http://ghw.spade-men.com/gpsdx.html.
If you compiled GSPd, you can run the following command in terminal
gpsd tty.PL2303-0000103D
or if you are using the GUI you might have to refresh the serial list, and then select /dev/tty.PL2303-0000103D
To see if it is working, you can telnet to your localhost, press “r” and enter and you should see some GPS data like so.
telnet localhost 2947
Trying 127.0.0.1...
Connected to localhost.
Escape character is '^]'.

GPSD,R=1
$GPGSV,3,2,12,17,47,258,,27,33,173,,24,16,189,,29,13,287,*74
$GPGSV,3,3,12,26,13,293,,19,05,056,,20,03,125,,04,02,199,*7A
$GPRMC,224206.00,V,3818.6285,N,08552.2345,W,,,200906,,,N*59
$GPGGA,224206.00,3818.6285,N,08552.2345,W,0,00,0.0,,M,,M,,*4F
$GPGSA,A,1,,,,,,,,,,,,,,,*1E
After that you can select GPS under Preferences, and choose GPSd in the drop down. After words you should have GPS working in OS X with the UT-41.
