Wifi

Overview

The F256 needs extra hardware to talk to Wifi.

There are currently two paths to this,

1. Have a wifi chip module installed onto the motherboard. (You can now configure this as an option when you order, Stefany will install it)

2. Connect the DB9 serial port to a modem

Then, you need to access wifi from the device.

TheOldNet device

These instructions are for Serial Wifi Modem for Vintage Computers V4.

Manual for that device: http://theoldnet.com/TheOldNet%20Wifi%20Modem%20Manual.pdf

This device is a wifi adapter that requires separate micro-USB for power.

You will also need the following,

• The unit itself
• A way to supply power to it over micro-USB. e.g. Kindle charger, USB-to-microusb cable connected to a computer.
• A way to connect your computer to the DB9 serial port on this device. e.g. PCIe serial adapter, USB-to-DB9 adapter cable.

We will need to configure it for your wifi network against your computer before we connect it to your foenix. (At some future time we will have a serial terminal in the F256k so we can do this from that device.)

On linux,

• Install GNU screen (e.g. sudo apt install screen). Below, you will need to run it as root so it can access raw hardware.
• 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.
