=== TheOldNet device, Hayes setup ===

These instructions are no good for F256K at the moment because the kernel does not support Hayes instructions. It may in the future, so I am keeping the notes around.

These instructions are for [https://www.tindie.com/products/theoldnet/rs232-serial-wifi-modem-for-vintage-computers-v4/#specs|RS232 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.

This is what you need,
* 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.
