<DIV><FONT face=Arial size=2>Ever have one of those days ?</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>1. I have a little plug pack with a variable slider
12V, 9V etc</FONT></DIV>
<DIV><FONT face=Arial size=2>2. The plug pack powers a PIC development board
(PIC and MAX232)</FONT></DIV>
<DIV><FONT face=Arial size=2>3. The development board has a MAX232 on board
which I am using to send to the laptop.</FONT></DIV>
<DIV><FONT face=Arial size=2>4. Data was coming in on the radio chip, and 5
volts logic was being presented to the MAX232. (used a CRO)</FONT></DIV>
<DIV><FONT face=Arial size=2>5. Tried a different USB / Serial converter - same,
no data in hypertrm</FONT></DIV>
<DIV><FONT face=Arial size=2>6. Reboot windows.</FONT></DIV>
<DIV><FONT face=Arial size=2>7. It turned out that the little plug pack had slid
from 12 volts to 9 volts.</FONT></DIV>
<DIV><FONT face=Arial size=2>8. It was enough for the little LED cct to show it
was working, but not enough to get the MAX232 to work.</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>Annoying.</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>Loop back on serial worked - just to confuse me
even more.</FONT></DIV>
<DIV><FONT face=Arial size=2>Looked on PIN 2 with a CRO and saw data - but the
CRO ust a high Z and did not load up the cct.</FONT></DIV>
