yes, maybe i have to check it´s funcionality. this would be the more difficult part. but i will try my best. thanks

thanks for replying! indeed it is a serial port from the motherboard and no adapter. the bios settings look allright (irq 4; 03f8-03ff) and there´s only my ps2 mouse installed. but i once tried it with a serial mouse (to check the port), that didn´t work,too. maybe i have to compare my com-port settings with the settings in my office to get a hint. but thanks anyway chris

hi! i have a garmin etrex h gps with a serial cabel (homemade). at my office (windows xp) i can copy geocaches to my gps via the "geocaching.com" interface. at home i get the error message, that no gps was found. i have easy gps at home, too. i get the message, that the serial port could not be opened. the cable must be allright, otherwise it would not work at my office. so there must be something with the serial port, that i never used with other devices before. there´s no error in the hardware manager. anyone has an idea, what i can try? thanks chris
