Think of it as an embedded telnet device on your serial port, because that's pretty much what it is. If you already have Internet connection on your Amiga, it's really not if that much use compared to just using telnet command or telser.device along with Term, NComm, VLT etc. Speed is limited by the serial port used, the CPU and serial.device, don't expect much more than 57600 baud, maybe 115200 if you have 060 and some luck. More typical will be 19200. A fraction of the speed you get with Plipbox. You use AT commands to configure the ESP, to set serial speed, to configure wifi and the IP stack.
