2 | This file is part of the GSM3 communications library for Arduino
|
---|
3 | -- Multi-transport communications platform
|
---|
4 | -- Fully asynchronous
|
---|
5 | -- Includes code for the Arduino-Telefonica GSM/GPRS Shield V1
|
---|
6 | -- Voice calls
|
---|
7 | -- SMS
|
---|
8 | -- TCP/IP connections
|
---|
9 | -- HTTP basic clients
