[sp] I have personally found Realterm quite good specifically for
     for attaching timing info to the prints received.

     It is available at: http://realterm.sourceforge.net/

     For measurement, I send the output directly to a log file - not
     displayed on the screen.

     BTW, Teraterm is my choice for regular use.
