Command: H
Function: Switch hook control.
Type: immediate
Arguments: No argument or an argument of 0 causes the 8400B
Plus Data Module to go on-hook.
S-Register: none
Example: ATH
Comments: The H command with no argument can be used during a
data call to cause the 8400B Plus Data Module to go
on-hook (hang up) after using the escape sequence
(+++) to return to command mode. An argument of 0
produces the same result, and an argument of 1 is
accepted but causes no action.
