			== Crash diagnostics ==

	~~== Other Hardware ==~~		If the ESP-8266-01 reboots for any reason it will report a "rst cause: " with one of the following numbers.
			# Normal power on reset
	~~In addition to controlling~~ the ESP-01 Wi-Fi module, the .UART command also provides facilities to use the serial connection port, either directly through some form of serial converter (e.g. a USB to TTL serial) or standard RS232 module (probably based on the MAX232).		# Hardware watchdog - kernel hung
			# Software watchdog - uncaught exception
	~~A USB serial connection allows you to do all sorts of clever things -~~ it ~~is possible to connect up to~~ a ~~PC like this for transferring data. In fact if you were an early purchaser you probably bought one~~ with ~~your ESP-01 as it is the one needed to program it.~~		# Software watchdog - watchdog hung, kernel called "system_reset"
			# Software restart
	~~If you use~~ one of the ~~easy to get TTL modules then you can communicate with PC's and other older machines - E~~.~~g. a real Spectrum with Interface 1... KevB is using one for his PC - see article~~ on ~~the forum at https://www.specnext.com/forum/viewtopic.php?f=6&t=895~~		# ESP woke from deep sleep

	It should be possible just to hook up to an external Raspberry PI for example and use a serial console connection allowing you to use the ZX Next as the keyboard... as the voltages match it should be fine just to connect the UART RX/TX and GND to the PI's PIN's 4/5/6 GND/TXD0-~~GPIO14/RXD0~~-~~GPIO15. See https://elinux.org/RPi_Serial_Connection~~

	~~There is a diagram of the GPIO header here: https://elinux.org/RPi_Low-level_peripherals~~

Xalior: Removed Pi3 notes, because that implies we support the Pi3, if we start to document all the things we don't support we'll be here forever.
