Using Modems
Set a unit number between 0 and 31. Other items must be set exactly as shown above.
Modem Settings
This section describes example modem settings. Perform an equivalent setup by referring to the user's manual for
your modem.
Note 1. For the modem at the PC, always store the settings in the nonvolatile memory in the modem.
2. In this section, the procedure for storing the settings in the nonvolatile memory in the modem is de-
scribed. This procedure does not necessarily have to be performed for the modem at the computer. If,
however, the settings are not stored in the nonvolatile memory, the modem will need to be set up using
AT commands from the communications software each time a communications procedure is started.
Setting Items
The items shown in the following table must be always set.
Other setting items differ according to the telephone line type, modem type, and so on.
Set each item according to your system as described for specific modems.
