I cannot access the serial port, COM1. Windows 7 Alienware 64 Bit Iso Free Download. I used to be able to but now any app, such as Hyperterminal, that tries to open COM1: puts up a small info window that says 'Unable to open COM1. Please check your port settings.'

Dear user try these troubleshoots to fix your problem:- >try to disconnect your modem and restart your device then try to re-connect it again >try to uninstall the modem settings from your device and re-install it and check if it is working >make it sure that your connection settings is correct >make sure that your modem is not.

Any idea what might be causing this? According to Device Manager the port is working correctly. I'm wondering if another auto started app that I don't know about has opened the port. Is there any way to find out what apps have opened the serial ports on the PC? I'm running Win XP home with all service packs and updates.

Any help really appreciated.
