Display Controller and
Modes
Display controller
The display controller interprets software commands into hardware commands that
turn particular pels on or off.
The controller is an advanced Video Graphics Array (VGA) that provides Super
VGA (SVGA) and Extended Graphics Array (XGA) support for the internal LCD
and external monitors.
Two models are available:
❑13.3 XGA, 1024 horizontal x 768 vertical pixels
❑14.1 XGA, 1024 horizontal x 768 vertical pixels
A high-resolution external monitor connected to the computer can display up to
1600 horizontal and 1200 vertical pixels at up to 64k colors or 1024 horizontal and
768 vertical pixels at up to 16M colors.
The display controller also controls the video mode, which uses industry standard
rules to govern the screen resolution and the maximum number of colors that can be
displayed on screen.
Software written for a given video mode will run on any computer that supports the
mode.
The computer’s display controller supports all VGA and SVGA modes, the most
widely used industry standards.

Video modes
The computer supports video modes defined in the table below. If your application
offers a selection of mode numbers that do not match the numbers on the table,
select a mode based on mode type, resolution, character matrix, number of colors
and refresh rates. Also, consider the following points:
❑If your software supports both graphics and text modes, the screen display may
appear to operate faster using a text mode.
❑The LCD’s highest graphics resolution is 1024 horizontal x 768 vertical lines.
❑If a resolution greater than the display’s physical capacity is selected, the
display driver renders a virtual display.

AT Commands
In most cases, you will not need to type AT commands manually. However,
there might be some occasions when you will need to do so.
This chapter describes AT commands for data mode. Fax and voice commands
are taken care of by application software.
The format for entering AT commands is:
ATXn
where X is the AT command, and n is the specific value for that command.
After you type in the command press Enter.
Any command issued is acknowledged with a response in either text or numeric
values known as result codes.
All commands and command-values accepted by the modem are described in
this section; any entry other than those listed results in an error.
+++ Escape sequence
The escape sequence allows the modem to exit data mode and enter
on-line command mode. While in on-line command mode, you can
communicate directly to your modem using AT commands. Once you
finish, you can return to data mode using the ATO command.
A pause, the length of which is set by Escape Guard Time (S12), must
be completed after an escape sequence is entered, This pause prevents
the modem from interpreting the escape sequence as data.
The value of the escape sequence character may be changed using
register S2.
A/ Repeat last command
This command repeats the last command string entered. Do not
precede this command with an AT prefix or conclude it by pressing
Enter.

A Answer command
This command instructs the modem to go off-hook and answer an
incoming call.
Bn Communication standard setting
This command determines the communication standard CCITT or Bell.
B0Selects CCITT V.22 mode when the modem is at 1200 bps.
B1Selects Bell 212A when the modem is at 1200 bps  (default).
B15Selects V.21 when the modem is at 300 bps.
B16Selects Bell 103J when the modem is at 300 bps (default).
Result Codes:
OKn=0,1,15,16
ERROROtherwise
Dn Dial
This command instructs the modem to dial a telephone number. Enter
n (the telephone number and any modifiers) after the ATD command.
Any digit or symbol (0-9, *, #, A, B, C, D) may be dialed as touch-tone
digits. Characters such as spaces, hyphens, and parentheses do not
count. They are ignored by the modem, but you may want to include
them to make the number and modifiers easier to read.
The following may be used as phone number modifiers:
PPulse dialing.
TTouch-tone dialing (default).
,Pause during dialing. Pause for time specified in Register S8
before processing the next character in the dial string.
WWait for dial tone. Modem waits for a second dial tone before
processing the dial string.
@Wait for quiet answer. Wait for five seconds of silence after
dialing the number. If silence is not detected, the modem
sends a NO ANSWER result code back to the caller.
!Hook flash. Causes the modem to go on-hook for 0.5 seconds
and then return to off-hook.

;Return to command mode. Causes the modem to return to
command mode after dialing a number, without disconnecting
the call.
S=n Dial a telephone number previously stored using the &Zn=X
command (See &Zn=X command for more information). The
range is 0-3.
En Echo command
This command controls whether or not the characters entered from
your computer keyboard are displayed on your monitor (echoed) while
the modem is in command mode.
E0Disables echo to the computer.
E1Enables echo to the computer (default).
Result Codes:
OKn=0,1
ERROROtherwise
Hn Hook control
This command instructs the modem to go on-hook to disconnect a call,
or off-hook to make the phone line busy.
H0Modem goes on-hook (default).
H1Modem goes off-hook.
Result Codes:
OKn=0,1
ERROROtherwise
In Request ID information
This command displays product information about the modem.
I0Returns modem identity string and driver version number.

L2Medium volume (default).
L3High volume.
Result Codes:
OKn=0,1,2,3
ERROROtherwise
Mn Monitor speaker mode
This command turns the speaker on or off.
M0The speaker is off.
M1The speaker is on until the modem detects the carrier signal
(default).
M2The speaker is always on when modem is off-hook.
M3Speaker is on until the carrier is detected, except when
dialing.
Result Codes:
OKn=0,1,2,3
ERROROtherwise
Nn Modulation handshake
This command controls whether or not the local modem performs a
negotiated handshake at connection time with the remote modem when
the communication speed of the two modems is different.
N0When originating or answering, this is for handshake only at
the communication standard specified by S37 and the ATB
command.
N1When originating or answering, begin the handshake at the
communication standard specified by S37 and the ATB
command (default).
During handshake, a lower transmission speed may be
selected.

O0Instructs the modem to exit on-line command mode and return
to data mode (see AT escape sequence, +++).
O1This command issues a retrain before returning to on-line data
mode.

P Select pulse dialing
This command configures the modem for pulse (non touch-tone)
dialing. Dialed digits are pulsed until a T command or dial modifier is
received. Tone dial is the default setting.
