Re: Use HP serial interface to save/restore programs? Message #2 Posted by Marcus von Cube, Germany on 1 Oct 2011, 4:43 p.m., in response to message #1 by Harry Jacobson
No, you can only do this with the 34S firmware in place, not the original from HP.
There are provisions for supporting the serial I/O port in the firmware but this is not documented for the general user. It's more of a testing environment for HP. I'm pretty sure you cannot get to the programs or registers from the outside this way.
Once you press the Erase button on the cable the firmware is toast. Sam-Ba.exe has the nasty habit of clearing the RAM, too, so all your data is lost if you use this button.
