What is the capture command? What commands have a " in them? Do you have a specific example with more details of what you're doing?

i am sending the command via tcl port, not telnet. Some command need to use "capture", such as

capture "ocd_reg"

If pass the tcl statment to capture, such as echo "peter", then i need to escape the double quote. But i don't know how to

Thanks Peter

I see. I haven't used the TCL port for anything. You might try asking about this on the regular openocd user mailing list.

This seems like a generic TCL string escaping issue (not related just to the "TCL port" of OpenOCD).

@quantrpeter - The following suggestion has worked for me - escape curly braces ({ and }) in your original string, then wrap your string into a pair of curly braces: https://stackoverflow.com/questions/5302120/general-string-quoting-for-tcl/5302213#5302213

If the problems persists, please try asking on openocd-user mail list: http://openocd.org/discussion/mailing-lists/
