5.10.3 Modem Setup
This menu option allows the user to enable and set up a modem string for a modem connected to the RS232
port. A modem is not supported on the RS485 port. If enabled, the start up string is sent to the modem to set
it in the following mode:
• Use factory defaults
• Assume DTR is always on
•
Disable ALL responses to the com port
•
Auto answer on the first ring
• Connect at 9600 baud
•
Use memory profile 0
•
Store setup in memory profile zero
Not all modems obey the same instructions. The user can edit the default initialization string to work with any
“Hayes Extended Mode compatible” modem which may not be that compatible. There are two menu choices:
Modem Enable Enable or disable modem support
Modem String Edit the initialization string sent to the modem
