AT\J Auto-Reliable Fallback
This command allows you to select whether your modem (when operating in auto-reliable mode)
will use Constant Speed mode or Variable Speed mode. If, with \J0 selected, an error corrected
auto-reliable connection cannot be established with another modem, the modem will fall back to
Constant Speed mode.
Selecting \J1 will cause the modem to operate in Variable Speed mode. If an error corrected auto-
reliable connection cannot be established with another modem, the modem will fall back to
Variable Speed mode after sending the CONNECT message to your computer. The modem will
alter its terminal speed to match the connection speed to the remote modem.
