Would be a good idea, but I don't have that opportunity. One system is a printer, the other is a GSM modem. I'm sitting here warmin the chip with my soldering iron now. Wonder if it still works... What do you know!!! It does! I've established that it works at temperatures way abowe what I will ever be submitting it to. Now if it only works with the ioce cube :-) /me getting ice :-) Well... Looks like it's working. Wierd... I think I'll do some tests of my own. I'll make a loop that pulses a port and then use my meeter to see :-) This should be interesting...
