E[<n>] Command echo mode
Controls echoing of characters received from the host back to the host when in
command state. This also affects framing of responses. (See “Response and
Result Framing” on page 20.)
n may be one of two values:
• 0: Disable echo
• 1: Enable echo (Default)
H[0]
Note: The 0 parameter
(ATH0) is the only one
permitted. It is optional
and has no effect on the
command.
Hang up (disconnect)
GSM mode When operating in GSM voice, or CSD mode, ATH or ATH0
hangs up the call, disconnecting it. The modem goes from online condition to
offline condition.
GPRS mode When operating in GPRS packet mode, the ATH on-hook
command may be used to reject a network request for PDP context activation
announced by the unsolicited result code RING.
The modem responds with OK. If there is no outstanding connection request,
the modem responds with ERROR.
Note: This is an extension to the usage of the H command from the V.25ter
standard.
