D= Dial line occupied.

R= Ringing (R appears in same position as D).

S= Connection secured by security handshake. (S appears in same position as D. S and D may flash alternately).

TR =

Data Terminal Ready.

MR =

Data Set Ready.

 

RS =

Request to Send.

CS =

TD =

Transmit Data.

 

14.4, 9600, 4800, etc.

= Data speed in Kbps (thousand bits per second)

 

or bps (bits per second) (“idle” or H-01, H-14, etc. may also be

 

displayed in the data speed position; see text below).

TM =

Test mode.

 

ER =

Error (poor signal quality).

CD =

Carrier Detect.

 

RD =

Receive Data.

 

Codes beginning with H (such as H-01) in the lower left corner of the status screen indicate that the Modem is handshaking with another modem (attempting to establish a connection).

When the modem is off-line, the word “idle” is displayed in the lower left corner of the status screen.
