USB to DB9 Ctrl-Break ?

I have used a few USB->COM converter from different brands and they all work as you were using a normal COM port. i.e. you press "Ctrl+Shift+6, x".

....How

Which laptops and OS?

The only issue I've run into, is that the Mac OSX driver for the PT2303 chip (used many places for those $30 USB->Serial IOGear convertors) doesn't support sending break. You need a keyspan device to properly do break on a Mac OSX laptop.

Otherwise, the windows driver for that chip works for break (although the windows driver has other issues) as well as the keyspan driver on windows.

Good day Thanks for the post The suspend a Telnet session, enter the escape sequence Ctrl,Shift,6 X option is not what I am seeking. I am seeking an actual ctrl-Break to enter #rommon mode ....... Thanks again

If you're using hyperTerminal, make sure it is configured to send "CTRL" characters and not use them for Windows. This unfortunately will prevent you from doing CTRL-X,C,V for cut & paste, but I've never had any problems with sending CTRL-BREAK through a USB-DB9 adaptor.

Same. It works by pressing "Ctrl+Brea". Not sure which Terminal program you are using, but you can try TeraTerm Pro and there is an option to "Send Break" in the menu.

"Ctrl+Shift+6,

Are you sure you are using the right break key combinations. Here is a helpful link I think

I have an USB-DB9 converter for my HP laptop, for both hyperterminal and CRT it's business as usual...
