but the system info screen now shows model as 123456789123456789123456789123456789123456789123456789
and the serial no surprisingly is now showing DS10000001
if i do another *idn? after a reboot i still get the same as above, so I'm now thinking the serial that is displayed on screen, is not stored as a string but is decoded from the string you send it. but still that string is stored and retrieved from memory when you do *idn? or :info:serial?
Hi, just noticed that I probably have about the same problem as dimlow.
I got that same S/N after it broke, but changing S/N works, and is storable.
The model no. is corrupted, and on the status screen the display is distorted,
a ~8px wide white noise band from left to right over whole screen, about where the model appears.
Can't see if there are any letters behind.
When i run *IDN? i get the serial also as model number. When i run :INFO:MODEL? i get nothing,
and if I remember correctly, the serial interfaces stops working until after reboot.
When i try to set the model number it stays in some volatile memory until after reboot. It shows in *IDN?
But it still doesn't show in :INFO:MODEL?
(so it seems I could not write to that position in memory at all anymore, via rs232)
I seem to have no other problems, and can live with it, but if someone manages to dump a complete working firmware, and figure
out how to overwrite the existing one, I'd love to hear about it.
Stupid me should have made a good cup of coffee before starting to hack.
At least it's not totally bricked.
