Read the instructions - [[Работа с последовательным портом из Linux/en|Working with a serial port from Linux]]. Note the settings: 115200, 8N2, '''no hardware flow control'''. | |||
For interactive mode: | |||
* | *run '''minicom''' with the following key that creats the job profile to the port (transmission speed, parity, etc.): | ||
<pre> | <pre> | ||
$ minicom -s /dev/ttyGSM | $ minicom -s /dev/ttyGSM | ||
</pre> | </pre> | ||
[[ | [[Файл:Minicom_settings.png|Minicom Settings]] | ||
* | * Go to settings (press ''Ctrl+A'', then ''O''), select ''Serial port setup'', set port ''/dev/ttyGSM'',set speed and parity - ''115200, 8N1'', ''Hardware flow control - No, Software flow control - No'' | ||
* | * Save settings: ''Save setup as _dev_ttyGSM'' | ||
* | * Then run as '''minicom /dev/ttyGSM''' (all settings will be taken from the profile name ''/dev/ttyGSM'' that we previously created) | ||
* | * Your first command should be ''AAAAAAAAAT'' - the module automatically detects the communication speed (see [[Special:MyLanguage/SIM900R|SIM900R]]) | ||
* | * With the second command, simply run ''AT''. You should get the answer '''OK'''. | ||

=== | ===Multiplexing ports=== | ||
The modem supports multiplexing mode which creates virtual ports,you can simultaneously work with the modem via these ports. For example, one port can be used to open a PPP session for GPRS, another - to receive and send SMS, check the balance, etc. see [[Special:MyLanguage/CMUX|CMUX]] for details. This mode is not supported for 2G modems. | |||
