the unit momentarily displays the
power-on screen, which typically
looks like this:
D=Dial line occupied
R=Ringing (R appears in same
position as D.)
S=Connection secured by security
handshake (S appears in the same
position as D. S and D may flash
alternately.)
TR=Data Terminal Ready
MR=Data Set Ready
RS=Request to Send
CS=Clear to Send
TD=Transmit Data
14,400, 9600, 4800, etc.=Data speed
in bits per second (“idle” or H-01,
H-14, etc. may also be displayed in
the data speed position; see 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 same position.

the support group the software
revision levels of your unit.
The modem spends about two
seconds checking the ROM
