hi,
i wanted to control something through 8051 by interfacing it to my pc through hyperterminal. a simple diagram is shown:
PC(hyperterminal) <----> 8051 <----> [something to be controlled]
actually what i am after is the interface between PC & 8051. the interface to the something to be controlled is not a problem since it would vary on the application
here are some of my thoughts:
- i will use 8051 serial port since it is interfaced w/ pc serial
- i will only use 2 lines, tx & rx
from these thoughts, these questions rose:
- is it possible not to use AT commands?
- as a support to the previous question, can i develop my own commands such that what i can see in the hyperterminal window is a prompt that waits for a command?
- are the tx/rx lines from the serial port enough for the operation previously described? or do i still need to use the other control lines of the pc serial port?
