Not with the meter, for two reasons: (1) I can't easily put the meter on it except under no load, which isn't a very useful test, and (2) I figured if it worked enough to get link on the Ethernets and get the behaviour I described out of the front-panel lights, it should at least drive voltage on the transmit pin of the serial port. Of course, I don't know the circuitry backing the serial port. But most serial ports in my (admittedly limited) experience always drive voltages on their transmit lines whenever they're powered up. I'll see how much work it would be to get to the points on/near the power connector that will let me measure the voltage under load. /~\ The ASCII Mouse \ / Ribbon Campaign X Against HTML [email protected] / \ Email! 7D C8 61 52 5D E7 2D 39 4E F1 31 3E E8 B3 27 4B _______________________________________________ Soekris-tech mailing list [email protected] http://lists.soekris.com/mailman/listinfo/soekris-tech
