The router was working the last time i used it (different O/S)

1) Go to device manager and select view hidden devices. Sometimes Win2k will install phantom ports even if disabled. I had this problem with IR ports on com2 which are not enable in bois, but still Win2k installed drivers and resources. Messed up myprinter and parallel port Zip.

2) What are the com1 port settings? Are they compatible with the router settings. Flow control, baud rate etc.. May need to dig out the router manual.

3) Do you have an internal modem grabbing the port?

4) Try a serial mouse to eliminate hardware problems.

Good luck, hope this helps.

Let's start with first things first. You say you are trying to open the "profile for the router". Does this mean that you saved a session? If so, are you sure it is configured properly? You can right click on My Computer, go to properties, clickon the Hardware tab, press the Device Manager button, scroll down to Ports (Com & Lpt) and see what Com ports are installed. Start a new session in hyperterminal and use that port. If this doesn't work, go to the BIOS and ensure that the serial port is set to the same com port number you are using. Do you know the IP of the router? You could also telnet to it, unless you have it set to not allow telnet sessions.
