* Identify the serial port, either through syslog or else trial-and-error. If you have USB-to-DB9 it may be /dev/ttyUSB0. With a card, it will be /dev/ttySX.
* sudo screen /dev/ttyS4 300
* If you get gibberish, kill screen (ctrl+a, k), reset the device (button), wait one second, restart screen.
* If you want instructions, type "AT?"
* Set your network SSID: AT$SSID=WIFISSID
* Set your network password: AT$PASS=WIFIPASSWORD
* Connect: ATC1
* If you need to see the configuration in the unit, AT&V
* Save: AT&W
* Set serial baud rate: AT$SB=115200
* Kill screen (ctrl+a, k)
* sudo screen /dev/ttyS4 115200
* Save: AT&W
* Show details: ATI
You should now be able to connect to the unit from wifi on your home network.


It is now ready to be connected to your F256K.
There will be a way to install a SLIP firmware on these, but I have not yet tried that.

Overview[edit | edit source]

The F256K needs extra hardware to talk to Wifi.

Be aware that in the retro scene, there are broadly two types of connectivity,

1. Via SLIP. This is supported by the F256K kernel.

2. Via Hayes commands (AT commands). This is currently not supported by the F256K kernel.

Here are some options to get your F256K system connected,

1. Install a Feather wifi board onto the F256K motherboard. (Now available as an order option - then Stefany will install it)

2. Use a Null Modem Cable to connect the DB9 port to a linux box, and configure SLIP on the linux box. (technicality: this is not wifi, but you will have network.)

3. Connect to an external device via the DB9 serial port. If the device ships with a Hayes firmware, you would need to replace it with a slip firmware.

Then, you need to verify connectivity.
