i would be very gratful if you’d get back 2 me please…!

thank’s mark

You still need to convert the rs-232 level signal to a LVTTL (3.3V) signal, so you still need a level converter, such as the MAX3222 above. Hope this helps. Jengr,

Does it differ from TTL to RS232 converter ? Thanks Dear Sir:

Thanks! I'd never seen this blog before I caught this project on hackedgadgets. I like it... you're doing a great job! btw... I like to see bare circuit boards... the sight of open, electronic magic makes me happy! :) k. Thanks!

The datasheet suggest 0.1uF so those will work as well as larger caps. I used 1uF just because I had them around. The datasheet suggest 0.1uF so those will work as well as larger caps.
