Modem Requirements
The 6416SW module supports the use of dial-in modems with the following
requirements:
The modem must be 100% Hayes-compatible.
Any valid baud rate (300, 1200, 2400, 4800, 9600, 19200) may be used. 2400 and
9600 are recommended.
The modem must be set to Dumb/Auto Answer mode.
Modem Configuration
To configure a modem, enter the following commands from the console to which the
modem is attached:
1. Type at&F and press Enter (to restore the factory default settings).
2. Type at&d and press Enter (to ignore changes in DTR status).
If you have enabled automatic modem hangup with the SET TERMINAL HANGUP
ENABLE command and want to keep this setting, enter at&d2 and press Enter.
This sets the DTR parameter so that hangup remains enabled when DTR switches
from ON to OFF.
3. Type ats =1 and press Enter (to auto-answer on the first ring).
4. Type ats ? and press Enter (to verify the auto-answer if 001 is returned).
5. Type atq1 and press Enter (to ignore the result codes).
6. Type at&W and press Enter (to save the configuration changes).
7. Type at&Y and press Enter (to define the configuration as the new default).
8. Set the modem to Dumb mode (with command recognition disabled) by following
the instructions in the modem's user guide.
An example of an IBM 7855-10 modem configuration is shown in Figure B-6 on
page B-8.
