I’ve recently upgraded to Windows 7 Professional. Even though it is a major enhancement compared to Vista, I found out that the driver that I used for Vista can no longer detect my USB-to-Serial converter on Windows 7. I manage to find the solution while browsing the net and I would like to share my findings.

I got my USB-to-Serial converter to work after installing Prolific USB-to-Serial Driver. Click here to download it.

I came to know that HyperTerminal is no longer a part of Windows since Vista and I found Putty to be a very powerful alternative, besides terminal emulation, it is also a Telnet and SSH client. You can download it from their link here http://www.chiark.greenend.org.uk/~sgtatham/putty/ .

My Computer

To connect to your USB-to-Serial converter using Putty, first you must identify which port is allocated to your converter. To do this in Windows 7, Go to Start -> Right Click Computer -> Manage . Then Computer Management (Local) -> Device Manager -> Ports (COM & LPT) -> Prolifec USB-to-Serial Comm Port (COM3) . You should see your device listing similar to the image on the left.

Putty

Take note of the Com Port that your connector is using. You will need this information to configure your Putty. To connect using Putty to your device using the serial interface, firstly startup the Putty program. Enter the correct port at the “Serial line” input box. Then at the Connection type: choose Serial. Click on Open and your session should start immediately.

Serial Connection

Press on the Enter key and you should get some response from your device.

    Thanks for sharing your knowledge, it seems really helpful.

    In this senario, are you using the USB port of the host computer or its serial port?

    And about hyperTerminal and win 7; you can always copy the executive and library files of hyper terminal from a working win xp and paste it into your win 7. it definitely works.
