I'm using Putty to make a serial connection to a device. I need to send a Hex string on this session. How do I do this? The Hex String is FF7E414244

This is required to break the serial device into command interface mode...

From an XP machine, I can use HyperTerminal. And then on the serial connection, do a "send file", where the file has this hexstring entered using hex editing means. So this mechanism works.

But now I have a windows 7 with no hyperterminal. so I'm using putty. But now how do I send the hex string?

are you sure sending a "break" won't accomplish the same thing? if you right click on the title bar of your putty session you can do a send special and this is one of the options. – SpacemanSpiff Jun 21 '11 at 3:14
No its not the same as sending a "break". I want to send this specific hex string over on the serial connection and I have a win7 machine. So since I cant use hyperterminal, is there any other way to do it? (using putty or any other mechanism?) – Amit A Phatarphekar Jun 21 '11 at 17:27
Have you tried Kermit? It works on windows 7(according to the docs) and has send file support. – polynomial Aug 23 '11 at 0:33

Answering my own question - Cannot do it with Putty. Use TeraTerm instead. Make sure you send in "Binary" mode - there's a checkbox for it when sending a file using TeraTerm.
