4.28. Extended AT Commands
The extended AT commands are supported by the Si2494/39 and are described in Tables 11 through 13.
Table 11. Extended AT& Command Set (Command Defaults in Bold)
Command
Action
&$
Display AT& current settings.
&D0
ESC is not used
&D1
ESC escapes to command mode from data mode if also enabled by HES U70, bit 15.
&D2
ESC assertion during a modem connection causes the modem to go on-hook and return to com-
mand mode.
&D3
ESC assertion causes ATZ command (reset and return OK result code).
&F
Restore factory default settings.
&Gn
Line connection rate limit—This command sets an upper limit on the line speed that the Si2494/39
can connect. Note that the &Hn commands may limit the line speed as well (&Gn not used for &H0
or &H1). Not all modulations support rates given by &G. Any improper setting will be ignored.
&G3
1200 bps max
&G4
2400 bps max
&G5
4.8 kbps max
&G6
7.2 kbps max
&G7
9.6 kbps max
&G8
12 kbps max
&G9
14.4 kbps max
&G10
16.8 kbps max
&G11
19.2 kbps max
&G12
21.6 kbps max
&G13
24 kbps max
&G14
26.4 kbps max
&G15
28.8 kbps max
&G16
31.2 kbps max
&G17
33.6 kbps max
&Hn
Switched network handshake mode—&Hn commands must be on a separate command line from
ATD, ATA, or ATO commands.
&H0
V.90 with automatic fallback (56 kbps to 300 bps)
&H1
V.90 only (56 kbps to 28 kbps)
