I have had a few el cheapo ($15 or so) USB to RS-232 adapters. One of them worked for a 3 month stint, then I didn't use it for a year or so. When I went to use it again, it was dead. I bought another of about the same type; both Sabrent brand. Alas, I am very disappointed with the second one, as I have pretty good evidence that it results in data corruption. The evidence was gotten by downloading a DC waveform to an arbitrary waveform generator; it happened with two independent software tools. The same thing doesn't happen downloading to the same instrument over a GPIB bus.
Thus, I am looking for recommendations from folks for a high quality USB to RS232 adapter. I'd like to get an industrial quality unit that will last years, not the cheap junk again. I'd prefer hearing about a model/brand that you've seen working in a demanding environment for years.
Any suggestions? Since I have to pay for this out of my own pocket, I won't drop a kilobuck on it, but I wouldn't shy away from the $50-$150 range.
