I got a USB to RS232 adapter off eBay. I'm using it in Windows so it comes up as a COM port. The only problem is that the device appears as COM5, but all the old programs I have only work with ports COM1 to COM4. When I go to Device Manager, the device shows up as a COM port under "Ports", but when I got into the properties for it, it does _not_ give me the normal option of being able to choose the COM port number.
The adapter device is baby blue in colour and has a silvery white cord, here's an exact picture:
The reason I give a description and picture is that it seems to be a VERY common device sold all over the world by many different companies. So I'm wondering if anyone has a decent driver for it to use in Windows XP, a driver that will make it appear as though it were just another COM port (specifically allowing me to set it to COM1).
Sorry I know this post isn't exactly all about embedded systems but I've tried a few different drivers from the web and I haven't had any joy yet.
...or then again if anyone knows of a way of setting the COM port number in Windows XP, I'm all ears. I've tried the normal method of going into Device Manager and clicking properties on the port, but it doesn't let me choose the number for the port. Also it doesn't seem to have normal Windows Registry entries that would allow you to set the port number (e.g. HKEY_CURRENT_CONFIG\blah blah)
In other news, I also got one of those USB to Serial ATA adapters and it works perfectly, lightning fast transfer speed. I haven't tried it out yet on a drive that has partitions but I'll let you know how it goes.
