Ericsson ZAT 19.2 Operation Manual page 34

@ The remote modem responds and returns a tone, but
disconnects before the connection is completed. The
modem advises NO CARRIER, disconnects and awaits
further commands.
The modem waits up to 50 seconds on the carrier wave. If you
consider this too short, you may adjust the modem setting to 60
seconds. This is done with the following command:
ATS7=60p%|
If the modem is set to automatic transmission rate detection
(manufacturers setting OFF), it is possible If the modem is set-
up with automatic speed detection, you may come into contact
with Semaforum at another rate than intended. Check that the
automatic rate detection is OFF (In certain cases it can be
appropriate to switch off the 1300 Hz connecting tone since
some modems interpret this as the carrier wave in V.23 standard
and reduce the rate to this level).
Semaforum's PC may of course be out of operation although the
remote modem is functioning normally. You obtain the
CONNECT message, but all further attempts to come into
contact with the bulletin board are unsuccessful.
¢ The calling up procedure is interrupted for no apparent
reason
The modem received a signal from the keyboard before the
connection was completed. You may, for example, accidentally
come into contact with a key while the calling up was in process.
The modem gives the OK or the NO CARRIER message,
disconnects the line and awaits the next command.
Vou ma y deliberately use this procedure to interrupt the
calling procedure. Just press any key and the operation
will cease.
2.11.6 Problems after the connection is made
You have hieroglyphics on the screen
The modem has succeeded in the connection to Semaforum
BBS, but you receive unreadable hieroglyphics on the screen.
