1    /BREAK

       /BREAK=break-character

    Specifies a character sequence that you can use to interrupt the
    signal being currently transmitted. To interrupt the signal, type
    Ctrl/break-character. You can select any ASCII character from @
    though Z, except C, M, Q, S, and Y. The default break character
    is ~.

2    /DISCONNECT

       /DISCONNECT=disconnect-character

    Specifies a character sequence that you can use to terminate
    DIAL_OUT mode. To disconnect the call, type Ctrl/disconnect-
    character. You can select any ASCII character from @ though Z,
    except C, M, Q, S, and Y. The default disconnect character is \.

3    /SWITCH

       /SWITCH=switch-character

    Specifies a character sequence that you can use to switch the
    line to PPP mode. To activate PPP mode, type Ctrl/switch-
    character. You can select any ASCII character from @ though Z,
    except C, M, Q, S, and Y. The default switch character is @.

    Similar to the CONNECT command, this qualifier switches a
    line into PPP mode. If the packet negotiations fail, PPPD
    exits and the line is left in terminal mode. If line is set to
    /MODEM and /NOHANGUP, this can result in extraneous data, the
    ASCII representation of Internet Protocol (IP) packets, being
    transmitted across the open line.
