Re: [M100] M100 power requirements

[Josh Malone]

I noticed no change in the power draw on my 102 when using the serial port,
although it wasn't actually connected to another device.

Hi,

My posts have been going into /dev/null and I finally fixed the email problems. 
 The webmail server was using the 'official' university address (without the 
mykopat) so my posts went into the  trash.  Just want to see if I have fixed 
things at the mailing list.

Guess I could always join twice with different email addresses but then I would 
get 2 copies of everything..
