I am learning about interfacing the 8051 with my laptop.
I have a few questions, and as helpful as you all have always been, I hope you will kindly contribute in clarifying the matters for me.
Just reading up on what Hyperterminal is and what is does. I've managed to open up the blank text window where you can type.
Three questions I have at the moment:
1) Whatever I type there, is it sent serially through the TxD pin of my serial port? So if I type letter 'A', the ASCI binary equavalent will be sent serially with start and stop bits?
2) What if my uC sent the letter 'B' to the RxD pin of the serial port. Would the letter 'B' come up on the screen?
3) So its not about a special language on Hyperterminal, it is merely to display what is received, and display what is sent?
3) But who controlls the DTR, DSR, CTS and RTS pin of the serial port?
If any one knows any links to good beginners tutorials on this, please kindly pass it over.
Many thanks.
