Verified Purchase
Works as advertised.
I didn't think this device would work because I needed it for a very old serial application, but it actually works perfectly.
worked great
When I switched my OS to win 7 64 bit none of the old converters would work because no one supports the 64 bit software. This converter worked without a hitch after downloading the upgraded drivers. I was back on the air in minutes.
Works, but has a major bug
This item works well, but has a major glitch that might throw folks into a tizzy. For some reason, at 9600 baud, selecting 2 stop bits corrupts the incoming data. Even if I echo back one character at a time, from a terminal window, it loses framing and receives the bits apparently at a different baud rate. The fix is to obviously stick to one stop bit, and hope you don't need two -- ever. I hav verified that the data is actually being transmitted properly. The glitch is in the receiver. DON'T USE TWO STOP BITS.
