# SIM900 Go's package
This package uses a serialport to communicate with the SIM900 GSM Modem.

## How to install

- You'll need Golang v1.3+
- SIM900 Package uses the [serial](https://github.com/argandas/serial) package in order to communicate with the modem via AT commands, you will need to install both SIM900 and serial packages.

```bash
go get github.com/argandas/serial  # installs the serial package
go get github.com/argandas/sim900  # installs the SIM900 package
```

## How to use

- You'll need an available serial port, SIM900 boards usually works with 5V TTL signals so you can get a USB-to-Serial TTL converter, I recommend you to use the [FTDI Cable](https://www.sparkfun.com/products/9718) for this, but you can use any USB-to-Serial adapters there are plenty of them.
