Reset Hayes parameters
All of the Hayes dialing parameters and S registers remain even after the data
call is complete. Similarly, if the dialing mode, keyboard to Hayes or vice
versa, are changed, the parameters remain as specified. The following
command allows you to reset the parameters and S registers to the defaults.
Entering 0 resets to the Hayes default, while entering 1 resets to the
downloaded operating parameters.
This command should only be used to reset all parameters. It should be
the last command entered, because all previous commands are
ignored.
