I have a Sony Vaio laptop that came with Windows XP. I hooked in a peripheral to the serial port and the software that comes with it won't communicate with the device. I tested it on my desktop which is running Windows 2000 and it worked fine. I ran HyperTerminal and connected to COM1. When I tried to type nothing happened (nothing showed up on the screen). If I connect to COM3 I can type (words show up). Is there some other software using the serial port by default or is there a known problem with the sreial port? I really need this fixed fast. Thanks!
Note: HyperTerminal successfully opens the serial port. It doesn't complain about it being in use or having any problems.
