For some reason I can not program the Voicemail via windows hyper terminal. The voice mail is connected to KXTD1232 and it is functional. My port setup is (9600 8 None 1 None). When the voicemail boot up, I can see the VM boot up status in the hyper terminal window (For example, card test 1..2..3..Online.) However, it will not respond to any of the keystroke(enter key). Does any one have a clue what went wrong?
