Regarding flow control in hyper terminal.

[Livingston]

RS-232 is often used with some form of flow control. This is a protocol, implemented through software or hardware, that allows a receiver of data to tell the transmitter to pause the data flow. This might be necessary, for example, if we
were sending data to a PC, and the PC had filled a RAM buffer: the PC would then
tell our embedded application to pause the data transfer until the buffer contents
had been stored on disk.


My question is
1. In which pin of db9 pc will sent the command to embedded application to pause the data transfer?

2. If i am using only two pin's (rx, gnd) from the pc how flow control will take place?.

Hi

you should use the flow control bins to do HW flow control.
also you can use SW flow control .
you can checkhttp://beyondlogic.org/serial/serial.htm and **broken link removed** for full details
