I'll try it. # Given an input string, adds backslashes as needed to create a # regexp that will match the string. proc string_to_regexp {str} { set result $str regsub -all {[]*+.|()^$\[]} $str {\\&} result return $result } > > If you think that's too much trouble, could you alternatively try "stty > > -echo" in expect, rather than send_gdb "shell stty -echo"? > > This was the original path I went down.

It's part of DejaGNU. # If the command is successfully started, a positive "spawn id" is returned. # If the spawn fails, a negative value will be returned. That spawn ID should suffice. I'd rather match the echoed text though. -- Daniel Jacobowitz CodeSourcery, LLC
