Dear all,

I need to control some device by the serial port of the 8051.

after sending a string, i need to put a "enter" signal to end the command.

i.e. ATD6543210; "enter"

my problem is that How can i send a "enter" command through serial port?



moreover, what is the difference between PC's serial port and 8051's serial port?

thx and regards,

Mario
