1.2.1 The Indicators
The indicators are on the front panel of the modem, which is shown in
Figure 1-1.
RUN
A continuous light means that power is on and the modem is
functioning correctly. A flashing red light indicates that a
test is being performed.
TXD
Transmit Data. A flashing light indicates that data is being
transferred from the local DTE.
RXD
Receive Data. A flashing light indicates that the modem is
sending data to the local DTE.
RTS
Request To Send. A continuous light indicates that the local
DTE is ready to send data. In full-duplex mode this is
normally lit at all times, but in half-duplex mode, only when
data is ready to be transmitted.
CTS
Clear To Send. A continuous light indicates that the modem
is ready to transmit data to a remote modem. In full-duplex
mode this is normally lit at all times, but in half-duplex
mode, lights shortly after the
RTS
indicator.
DCD
Data Carrier Detect. Lit to indicate recognition of a carrier
signal from the remote modem. In full-duplex mode this is
normally lit at all times, but in half-duplex mode, only when
the remote modem has control for transmitting.
