[time-nuts] another Ebay mixup, 5370

Well John, since you are asking for it (like I did not know the question 
was coming...)

I spent about an hour this morning trying to understand why 7470.exe had 
stopped working with my old Prologix controller, which has been assigned 
permanent duty as the 494P screenshot dude. The program would give me a 
cryptic (screen shot coming) error message and bail out. Prologix.exe 
does not even find the device, even though the virtual COM port shows up 
in Device Manager and the COM port shows up also in Prologix.exe.

It has been a while since I used it for spectrum plot. I have since 
worked quite a bit with Abdul's new controller and I thought I had 
somehow messed the configuration. So I reloaded everything from scratch. 
Same thing. So, since I have also bought a new laptop, I installed 
everything from scratch on the new laptop (WinXP Pro too). Same thing.

So I also tried the new 4.2 controller (not upgraded the firmware yet), 
and while Prologixc.exe recognizes it, I can't get a screen shot either 
(no error, it just times out with no message, the 494P is addressed, the 
LED turns on and that's it). I have not changed the config of the 494P, 
but I am wondering if the GPIB cable may be defective. It's a true blue 
HP cable, but everything is possible.

Soooooo, out of desperation, and because I actually had other plans for 
today :-) I took the digital camera. That always works...

By the way, I will bring the laptop next week. You are going to earn 
your free dinner :-)
