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 Si2493 can
connect. Note that the &Hn commands may limit the line speed as well (&Gn not used for &H0 or
