Chapter 4 - AT Commands
A complete AT Commands, S-Registers, and Result Codes Reference Guide can be found on the
MT5634ZPX-V92 CD and on the Multi-Tech Web site.
Fax Commands
Fax commands resemble AT commands, but are more complicated to use. Because of this, we
recommend that you use a fax program to send and receive faxes rather than attempting to control the
modem directly. Developers who need to know the fax commands for the MT5634ZPX-V92 can find Fax
Class 1 and Fax Class Class 2 Reference Guides on the MT5634ZPX-V92 CD as well as the Multi-Tech
Web site.
