hello, flks! I have a doubt... Is possible use php to access usb port on windows? because I spent some hours in google and I had not found anything... just to "com" port... and I tried some functions in my code like: dio_open, fopen, fwrite .... but these function run ok only with "com" (rs232) port... But usb is impossible I get errors all the time.... I wanna access a usb port cause I have a garmin gps ... and I'm wondering catch the data send by gps with php... to store in a db... :) will I need some dll to solve this problem??? I'm hoping for any suggestion... :) seeYa!
