Press Enter or Return.
After completing its tasks, the 3C882 ISDN modem sends a
message to the screen.
An AT command line starts with the characters AT. The
command line can accept up to 40 command characters in
the line (not including the two AT characters, or spaces).
Placing Multilink PPP Calls
Before you place a call, ensure that the Multilink PPP box on
the 3C882 ISDN modem Configuration dialog box is checked.
Also, the destination you are calling must also support
Multilink PPP. For example, if you are trying to dial into the
Internet, your Internet service provider must also support
Multilink PPP in order to successfully place a Multilink PPP
call.
Although this is not generally the case, your Internet Service
Provider may require an Endpoint Identifier Class and an
Endpoint Identifier. The Endpoint Identifier Class is
configured using S register 82. The Endpoint Identifier is
configured using S register 83. Refer to Appendix B for
acceptable values.
