AT#I V.22bis Leased Line
The ITU specifies that in V.22 and V.22bis a different handshake should be used for leased line
mode. This mode is specified by default.
Some modems still use the standard PSTN handshake for leased line connections.
Use #I1 to connect to these modems in V.22bis leased line mode.
Options
AT#I0 ■V.22bis leased line normal
