When I try to make a PSD call through dial-up using AT command atd*99#, what are the sequence
Hi,
When I try to make a PSD call through dial-up using AT command atd*99#,
what are the sequence of events that occur on PC side.
I am making dial-up on UART using RS-232 cable.
To be more specific, what are the sequence of AT commands that get
executed when we do dial-up for PSD call.
Also what are the signals that flow between DTE(PC) and DCE(modem)
during dial-up.
Please respond if anyone has any idea.
Regards,
Farhat
