Hello fellow Vee-ers;
I have a Vee program that sends and receives bytes over a serial port at 115K. I have it working great with my desktop that has a real com port. But every usb to com port adapter I have tried (I need this to run on a laptop) gives me a BSOD (blue screen of death) at some random interval. I have tried 3 different brands of Uarts/adapters and I made sure I was using the latest drivers, but I still cant get it reliable. It also does this on my desktop if I use the usb adapter (but not when using a real com port).
The other issue is of course the speed. When the program is running is it very slow using the usb-serial adapter. Since USB is much faster than serial, I wouldnt expect a bottleneck, but it sure does.
Here is my question: Does anyone here know what brand USB-Serial adapter is the most reliable? Has the best drivers etc?
I am using WIndows XP Pro and Vee 9.0
I have tried a Silicon Labs (CP2103) and a Keyspan adapter. I also tried a third one but don't have it around and don't remember what brand it was.
Any help would be appreciated.

Any USB-serial driver is an emulation process, so there will be speed loss regardless. Is it possible to tone down the baud rate on the device?
