+++

The purpose of the +++ command is to provide a way to switch the data module from on-line or data mode to command mode without disconnecting a data call that is in progress. As long as the call is not disconnected, you can return to the on-line mode with the O command.

This is one of the two commands that does not require the AT prefix (A/ is the other one), and it is never followed by pressing [ Enter ]. The value in S12 determines how long your keyboard should remain idle before entering the escape sequence, as well as the maximum allowable time between entering each character of the sequence. The character used in the escape sequence is determined by the value in S2 (default is ASCII 43, the plus sign).

Chapter 3, “First Time Users,” Chapter 4, "Operation and Configuration"; the O command in this appendix; S2 and S12 in Appendix B.
