How do you connect to remote BBS' with this? I have only done it with
telnet on a computer. How do AT commands work on wifi? Does the
device have a SIM card and, of so, are the remote BBS' still using
modems??
The remote side is a telnet server running bbs software. You can telnet
to it using any telnet client.
On the client side, the device connects to wifi, not the cell network,
so no sim card.
And the device is essentially a telnet client, meaning the device does
the tcp/ip and the telnet protocol with the telnet server, just like how
a regular modem does all the v.42bis handshaking and error correction
and compression with the other modem.
You control the device with AT commands, both to get connected to wifi
and to "dial" some telnet server.
How exactly the AT commands work is what the manual is for. You just use
them the same as with any other modem. There's commands to list all wifi
networks in the area, supply a password to join a network, set static IP
settings or dhcp, even to control the led. The ATDT command accepts an
ip or hostname and tcp port number like "hostname:port" instead of a
phone number.

Every modem ever made had it's own special AT commands for various
functions. This is no different.
