SERIES II INTELLIGENT DATA/FAX MODEMS
Figure 5-2. On-line diagnostics information.
On or Off Hook H
You can make the Series II Modem hang up (go On Hook). Entering
ATH1<CR> brings the line Off Hook, just as if you picked up the
telephone set. You can hang up by entering ATH0 or ATH (the default
is 0 when no number is entered).
Escape Sequences- Entering Command Mode While Still
On-Line +++AT<CR>
It is possible to cause the Series II Modem to enter Command mode
after the modem has gone on-line with a remote modem without
disconnecting the call. This is done by entering an Escape Code. The
default Escape Code used by the Modem is three plus signs (+++)
followed by the letters A and T, up to sixty command characters (most
typically “H”, to hang up), and a RETURN. The number of command
characters allowed after +++ AT<CR> , is defined by S-Register S34.
S-Register S34 defaults to ten command characters.
