Thanks, Humberto, but it still won't open COM2, even running as administrator. July 12, 2012 by raildoc When I first used PuTTy, it worked fine. After I (succesfully) reprogrammed a 168, It absolutely will not open again. Yes, I set Serial 115200, one, none, none and used the same Port5 that I used for programming and admin-ID'd myself. Putty session opens to black screen. And this is what I get upon clicking Open. Any other ports on the front of the switch won't give you a serial connection.
Putty Error Unable To Open Serial Port
OK, Details;
I'm trying to communicate to the console ports on several Cisco switches and routers. I my computers do not have a 9pin Dconnector that will connect to a standard Cisco console cable, and the Cisco devices do not have USB.
Therefore, I purchased a Belkin USB to DB9 converter for serial connections. It's nice because I can see LEDs light up on it when it transfers data (link, TX, RX).
This has worked for a while. I'm using a home built computer using an AMD Athlon II comptuer with four USB ports comming off the motherboard. It's running XP OS.
Microsoft Windows XP
Professional
Version 2002
Service Pack 3

This has been working for a year or so, and right in the middle of running it just stopped working and was hung. After that, when I use the Device Manager to list the 'Ports (COM & LPT)' it now only shows COM1 and LPT1.
I get the above error message when ever I use 'Putty' software to do the serial terminal emulation.

Not sure if it was my Belkin device, Computer, or OS.
1) So I first tried rebooting the computer, with no success.
2) I tried connecting to another router with no change.
3) Next rebooted the orginal router, no change.
4) Rebooted the laptop, no change.

I searched the internet for this, and the best advice was to manually install the com port. I tried this, but it instead installed COM4 and COM5. I tried anyway, but uninstalled when done.
How does the COM3 port get built? Should it always show available, or does it build the interface when a device is plugged in?
Well, I haven't messed with it over the weekend, tried again today, and now it's working when I plugged in the belkin USB to Serial DB9 connector. It recognized the device and gave a 'bong' and it appeared. Therefore I susspect that it is built when the device is plugged in, and torn down when it is disconnected. Not sure why it's now working....but now i don't trust when it may go down of back up. I'm sure there is a logical explaination, but not any help from the MS OS.....as usual.

Maybe the Belkin device is flakey, but unlikely due to the number of times I unplugged and replugged......not sure.
I then grabbed a Laptop running Windows 7 and connected to it's USB port, and running putty software, and it started working.
Then, in about 5 minutes, it hung up as well, and I could not see the COM3 Port.
