Note
: When using hyper terminal to program a modem, PC COM port settings must
match the baud (interface data rate), parity & stop bits parameter settings of the
module.
Note
: Do not send commands to the module during flash programming (when
parameters are being written to the module registry).
Wait for the OK system response that follows the ATWR command before entering
the next command or use flow control.
