89v51rd2 serial communication

[AMit]

I dont know how it worked …the concept…but i tried this and it worked..

 

* I grounded the Tx ping while blank check and it went through.

 then I left Tx pin as it is (now not gorund) and programmed it and the controller got programmed.

 

Any ways thank for sujetion.
