How to resolve this issue, as I have tried many alternatives but no any settings found for this issue that could detect the router with USB, kindly help me out with this as well, that if I am using Windows Vista, that has no any hyperterminal in it, so how to deal with Router/Switch IOS, I mean should I use Teraterm/Secure CRT or anny built in utility is available in Vista.

Hope to make you understand well

  Download Tera Term and use that works great for that . Also  buy yourself a db9 to usb converter if you don't have a com port, most newer laptops do not . This setup will work fine , use it all the time  when we have to be in the console.  Plug the console cable into the console port and the db9 end goes into the db9 to usb converter and then plug that into the usb port on your laptop or pc .

For some reason Microsoft decided to remove HyperTerminal from Windows Vista. Hilgraeve, the company that wrote the HyperTerminal app included in previous versions of Windows, also has a downloadable HyperTerminal Private Edition.

So if you are running Vista and need HyperTerminal to setup a CAG, router, switch, etc, you can get it below -

And as far as issue stated by you get usb to db9 coneverter and with terterm or secure crt application you can take console for the router by selecting following parameters

  • Speed - 9600
  • Data Bits - 8
  • Parity - none
  • Stop bits - 1
  • Flow Control - none

and check out the below link for USB to DB 9 converter hope that helps out tour query !!

Hello Samiullah,

Since you are using the USB port on your PC, try using COM 4 when setting the property on your terminal.

I also have a new laptop that does not have DB-9 on it and have to use the USB port with COM 4.
