Programmer’s Guide Intel Confidential 5
1. INTRODUCTION
The MD566X Programmer’s Guide describes the software interface of Intel’s V.90/V.92 56K
solution. The programmer’s guide includes the AT command sets for data, fax, and voice and the
16C450/16C550A UART emulation. The programmer’s guide should be used with the following
Intel publications: the MD566X Datasheet, the IS-101 Voice Application Note, and the Class 1 Fax
Application Note. Please note that supported AT commands are firmware revision-dependent.
IMPORTANT: The AT commands in this document are supported by firmware versions
6.06 and above for V.90 and 7.XX for V.92.
Like the earlier solutions from Intel, the V.90/V.92 56K family of products supports a variety of
applications without the need of additional firmware development. The MD566X solutions
described in Table 1-1 are currently available except as noted.
