[ltp] Serial port for a T40

[Joan Roig Amorós]

Hi, 

does anybody have any experience connecting a GPS unit to a T40 running linux? 
of course my T40 has no serial port, so... what is the best/cheapest way to 
add a serial port that will work also with linux? serial to USB? PCMCIA to 
serial (I see that cards  are ~$25 in ebay)? or should I wait for Xmas and 
buy myself a dock?

thank you,

joan
