+++ escape char doesn't work


Hi to everybody !
I am using GR64 R4A software release.
When the modem is connected giving +++ escape sequence it doesn’t go to command mode.

Any suggestion?


There needs to be a 1 second pause before and after issuing the sequence “+++”.




I know that 1 second guard time shoul pass before and after but even with this it doesn’t work.
I use only tx, rx and GND for modem comunications.


Have a look to the config of the commands: ATS12, ATE2EST and ATE2ESC , you may find a wrong configuration of your escape sequence.
