Hyperterminal Commands Rs232

Dear Srini, Check whether the following setting is enabled to see characters typed locally. Properties settings ASCII Setup Echo typed characters locally.

Once the connection becomes okay you will see every typed character twice. Don't worry you are not seeing double but every character is being echoed locally as well as by the device you are connected to.
