I got some things to look out for before I put in another code

Hans van Pelt I was trying to keep sending 'r' without control char.

Yes, why not... you cannot see control chars anyway. only 'r' is visible, so why bother about invisible chars durint testing?
If you can send an 'r' you can also send the control chars... but if you only send an 'r' it is 1) very simple (does not get any simpler than this)
2) very visible on you serial terminal.



may be good coding comes after 20 days of continous work...

Good coding goes usually as follows: 19 days of studying and preparing and 1 day of coding.... Don't do coding without the first 19 days... If you do, you will end up with lots of code that does not do what you want it to do ..
