Seeing as this is my first post on here, I thought I'd make it a meaty one and it's had me stumped for quite some time. I have a device which runs via serial cable to my machine and interfaces with a DOS based program. I've recently upgraded my machine to a system running XP and as such have bought a USB > Serial adapter in order to continue using this device. I have had no problems installing drivers for this device and it's in full working order, along with the necessary software installing fine and operating as normal. The problem lies with the COM Port settings. On installation of the USB>R232 device, it defaults it's COM port allocation to COM8. Now for a DOS program to recognise it, it needs to be on COM1, COM2 or COM3. I've tried as hard as I can to alter the settings to one of these COM ports, but it's beyond my ability. I've come on here as a last ditch effort to try and get some help. Anyone that can help me out on this one will have my eternal gratitude. Thanks in advance.
