This should not be necessary in most cases, but, there are some 2400bps, 1200bps,
or even 9600bps modems you may not be able to connect to without using the
following method:
Using the +MS= command. AT+MS=V32,1,4800,9600,4800,9600 <enter>
will set the modem to use V.32 modulation, auto mode detection, with
9,600bps as the lowest transmit connection rate acceptable and the highest
transmit connection rate attempted. See “Setting up DTE bps” in the CDS-
9020 User Manual.
Analog Testing the CDS-902X Modem
Refer to the Analog Testing section in the CDS-902X User Guide for details.
To test inbound Data calls in Analog mode the user must go into the configuration
menu. Turn on option (N), Enable FAM (Forced Analog Mode). Be sure to turn this
command off after testing. If you forget to turn it off, you can call the unit remotely
and turn it off.
Trouble Shooting Analog Connections
The AT&V1 Command displays your analog Receive levels, etc. (Your actual speed,
DCE to DCE is displayed). These tests must be done in the analog mode, and the
connection must be from the Host Computer into the CDS-9022A, or call into a BBS
type of Host, or from the CDS-9022A into the Host.
Time required between dialing retries
(Redialing when you use the *ATDT11111111 command)
If you are in a CDMA coverage area the CDS-9022A will take anywhere from 5 to 7
seconds before it is ready for next inbound or outbound data call.
Note: when making an analog call, and the unit does not connect (CD does not go
TRUE), the CDS-9022A will reboot. This process can take up to 60 seconds in most
wireless provider’s systems. This time may be different if your PRL file is larger than
that in your wireless provider’s system.
