Even for amateurs ...

The card has been appointed for a new PC with the OS Win7 who had no accessible RS-232 interface. The installation was carried out without any problems, the card is immediately recognized and the Comports 3 and 4 assigned. , Other (free) Comports be determined by the settings. On this occasion I was able to discover connections on the motherboard for COM1 and COM2 that were simply not led to the outside and could be made available in the BIOS.
Incidentally, a second map was appointed a week later at Amazon right (a bit expensive), after the first purchase after 7 days of let's sells was still not arrived. As usual, Amazon delivered immediately prior to the first order ... The card runs without any problems for several months and connects wireless devices to the PC.
