This RS232 card would not work in my computer. Had to be updated with the Oxford Chip UART 16950. Also required power adapter from power supply to four pin connector on RS232 board. The card now works great as I use it for packet with APRS software. Please note: All computers are not the same. Thanks to Star Tech Techs they kept at it until problem was solved. John

Having purchased a new computer, I needed a serial communications card for use in my Amateur radio activities. After much research into the cards available, this card meets the criteria I was looking for. My old computer had a similar card and it functioned perfectly. I have not installed the card yet but it is compatible with my control software.
