If your software does not support
modem control, you must
configure the access server line to
which the modem is connected
with the
no exec
line
configuration command. Clear the
line with the
clear line
privileged
exec command, initiate a reverse
Telnet session with the modem,
and reconfigure the modem so that
DCD is high only on CD.
End the Telnet session by entering
disconnect
, and reconfigure the
access server line with the
exec
line configuration command.

noCTS noDSR DTR
RTS
There are four possibilities for the noCTS
string appearing in the Modem Hardware
State field:
•
The modem is turned off.
•
The modem is not properly connected
to the access server. Check the cabling
connections from the modem to the
access server.
•
Cabling is incorrect (either rolled
MDCE, or straight MDTE, but without
the pins moved). See Table 16-1 for
information on the recommended
cabling configuration.
•
The modem is not configured for
hardware flow control. Disable
hardware flow control on the access
server with the
no flowcontrol
hardware
line configuration
command, and then enable hardware
flow control on the modem via a
reverse Telnet session. (Consult your
modem documentation, and see the
section “Establishing a Reverse Telnet
Session to a Modem,” earlier in this
chapter.)
Re-enable hardware flow control on
the access server with the
flowcontrol
hardware
line configuration
command.
