Technical problem (OT)

Hallo allemaal,

I think I found the reason for my email problems. A bit further you 
see "bit......" and that was "bit baCC ngBB MMed". I think there is 
a porno filter active :)

I had to buy a TI-84 for my son for school. Quite interesting, it 
has a Z80 on board. It has a bit...... USB interface and another 
bit....... 2-line interface. This particular interface can be 
connected to the RS-232, please se:
The second site is Dutch but the schematic is more clear IMHO.

Why this email? I'm puzzled, I have no idea how this can work well 
with the LED between the two Grounds. 

If anybody can explain this, please! Thank you!
