Lights(ExternalModemsOnly)

Front-of-the-Case Lights (on All Non-Voice Externals and Some Voice Externals)

Symbol Meaning Status

AA............Auto Answer Answer mode: ON when register S0 is set to 1 or higher (Auto Answer),

and when answering a call; OFF when modem originates a call. Light

flashes when there is an incoming call.

CD.............Carrier Detect ON if modem receives a valid data signal (carrier) from a remote modem,

indicating that data transmission is possible. Always ON if CD override is

ON (&C0).

RD.............Received Data Flashes when modem sends result codes or passes received data bits from

remote.

SD..............Send Data Flashes when computer sends a data bit to modem.

TR..............Data Terminal Ready ON if modem receives a DTR signal from computer. Always ON (modem

ignores DTR) if the DTR override is ON (&D0).

CS..............Clear to Send ON until modem lowers CTS when Transmit Data hardware flow control is

enabled (&H1, &H3).

ARQ/ Error Control/

FAX..........Fax Operations Data Mode: Automatic Repeat Request. ON if modem is set to &M4 or &M5

and successfully establishes an error control connection. Flashes when

modem retransmits data to remote modem. Fax Mode: Flashes to indicate fax

mode.

TECHNICALQUICKREFERENCE

Top-of-the-Case Lights (on Some Voice Externals)

Light What It Means When Lit

POWER................The modem is turned on.

SEND...................The computer is sending a data bit to the modem.

RECEIVE .............The modem is sending result codes or passing received data bits from the remote.

ONLINE...............The modem is online. (NOTE: This light blinks when the mute feature is being

used.)

TECHNICALQUICKREFERENCE

TypingCommands

• Type commands in either upper or lower case, not a combination. Use the

Backspace key to delete errors. (You cannot delete the original AT command since

it is stored in the modem buffer.)

• If a command has numeric options and you don’t include a number, zero is

assumed. For example, if you type ATB, the command ATB0 is assumed.

• Every command except A/, +++, and A> must begin with the AT prefix and be entered

by pressing ENTER.

• The maximum command length is 58 characters. The modem doesn’t count the AT prefix,

carriage returns, or spaces.

NOTE: All defaults are based on the &F1Hardware Flow Control template

loaded in NVRAM when the modem is shipped. Defaults are listed in italics.

TECHNICALQUICKREFERENCE

BasicDataCommands

<control key>S

Stop or restart help screens.

<control key>C

<control key>K

Stop help screens.

$Use in conjunction with D, S,

or &commands (or just AT)

to display a basic command

list; online help.

AManual Answer: goes off hook

in answer mode. Pressing any

key aborts the operations.

A/ Re-executes the last issued

command. Used mainly to

redial. Does not require the

AT prefix or a Carriage

Return.

A> Re-executes the last issued

command continuously, until

the user intervenes or the

command is executed. forever.

Does not require the

AT prefix or a Carriage

Return.

Any key Aborts off-hook dial/answer

operation and hangs up.

AT Required command prefix, except

with A/, +++, and A>. Use alone to

test for OK result code.
