Bought to replace two port serial PCE card. I had problems getting Windows XP under VMWaare under Windos to recognize card serial ports for an old Singer Monogramming sewing machine. Gearmo 2 Port USB to Serial Professional Adapter works perfectly. Mission accomplished!

No problems with it, it uses a genuine FTDI chip and can indeed control two RS-232 COM ports at once
