Command
Display AT& current settings.
ESC is not used
ESC escapes to command mode from data mode if also enabled by HES U70, bit 15.
ESC assertion during a modem connection causes the modem to go on-hook and return to com-
mand mode.
ESC assertion causes ATZ command (reset and return OK result code).
Restore factory default settings.
Line connection rate limit—This command sets an upper limit on the line speed that the Si2457/34/
15/04 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.

Switched network handshake mode—&Hn commands must be on a separate command line from
ATD, ATA, or ATO commands.
V.90 with automatic fallback (56 kbps to 300 bps) (default for Si2457)
V.90 only (56 kbps to 28 kbps)
V.34 with automatic fallback (33.6 kbps to 300 bps) (default for Si2434)
V.34 only (33.6 kbps to 2400 bps)
