Command:
+++ Escape Sequence
Values: n/a
Description:
When the modem has established a connection and has entered online data mode, it is
possible to break into the data transmission in order to issue further commands to the
modem in an online command mode. This is achieved by the DTE sending to the modem a
sequence of three ASCII characters specified by register S2. The default character is +. The
maximum time allowed between receipt of the last character of the three escape character
sequence from the DTE and sending of the OK result code to the DTE is controlled by the
S12 register.
