At the local Astro Camp this weekend I discovered something interesting regarding my USB 2 RS232 converters which I thought it worth mentioning.
Using Vista, I have found that I need to follow the following procedure for any of the converters I have, and with the 2 I have tested it means they ALWAYS work. This may only be applicable to Vista.
1) boot up laptop
2) plug in USB->RS232 converter
3) open device manager and configure to COM 1, ignoring warning about "in use", as I don't have any other com ports.
4) reboot laptop with the adaptor left plugged in.
Upon starting up the laptop the second time, the serial connection appears to work no problems at all.
It seems a reboot is required. I suspect step 3 is not required but I haven't proved that.
Tested with Aten adaptor and a no-name brand one I've had for 5+ years.
