7.12 +++ Switch from data mode or PPP online mode to command
mode
+++ escape sequence is only available during a circuit switched data (CSD) call or a packet switched connection.
The +++ character sequence causes the EHS6 to pause data mode and return to AT command mode. This
allows to enter AT commands while maintaining the data connection to the remote device. By the way the same
task can be performed by toggling the DTR line if AT&D is set to 1. ATO is used to resume data or PPP online
mode.
To prevent the +++ character sequence from being misinterpreted as data, it must be preceded and followed by
a pause of at least 1000 ms. The +++ characters must be entered in quick succession, all within 1000 ms.
