during 1200 baud mode operation since the modem must process incoming and
outgoing data.
The value of each parameter is indicated with a yes or no response, except for the abort
character setting which is a hex value.
On initial power-up, the list will not show an entry for PH 0 NE N 0 : . The 10 bits-per-
word prompt is answered by the modem after receiving the wake-up command code
sequence. If you are using 7-bit words with parity enabled, the 10 bits parameter
responds with
Y,
or yes. If you use 7-bit words with no parity, the response is
N,
or
no
.
Of course, an 8-bit word with no parity is a 10-bit word (if you count the stop and start
bits). If you have a computer (or terminal) which transmits 8-bit words and a parity bit
(11 total bits) you will receive parity errors from the DC-2212 -
that is, if it locks
onto your wake-up sequence.
Each line of the parameter listing is terminated with a carriage return and a line feed.
If your serial communications software automatically assumes another carriage return
upon reception of a line feed code, the list will appear double-spaced

Originate mode operation
(default)
The modem will always operate in originqte mode when cold-started (initial power-up)
.
Use originate mode when you want to call a time sharing network, like CompuServe.
You can also use this mode to force the modem to automatically dial a telephone
number for you (while in the automatic mode)
.
To check that the DC-2212 is in originate mode
,
enter the list command
.
The list shows
0 RIG M 0 DE
:
Y :
"Yes, you are in the originate mode."
Answer mode operation
The
A
command places the DC-2212 modem in the answer mode of operation
.
Unless
you indicate otherwise with this command
,
the modem
is
defaulted to operate in
originate mode
.
Use the answer mode when you want to receive a call from a modem which is
operating in the originate mode
.
The status of the manual/automatic switch
determines
whether the DC-2212 will wait for the telephone to ring (auto-answer mode) or seize
the telephone line as soon as you exit the command receptive state with the X (exit)
command
.
