Controlling Automatic Feature Negotiation

The S-registers which control and specify a connection are described in the sections that follow. An overview of the connection options that can be set with S-registers is provided in the chart below.

and AFT

For example, the AT&Q5 S44=3 S46=6 S48=0 <CR>command establishes a synchronous X.25 connection with either a packet-switched network or a remote Vseries product that supports X.25. See the S - Register listing.
