+## Console Takeover
+
+If your system has more than one character unit, then the Boot Loader 
+will "poll" all of the character devices for a request to make any of 
+the alternate character devices the active console.  This is called a 
+console takeover request.  This functionality must be enabled in the ROM
+build configuration, but currently it is for all standard ROMs.
+
+To request a console takeover, you just press the \<space\> character 
+twice in a row at the port or terminal that you want to move the console
+to.  The terminal or communication software **must** be configured for 
+the default serial port speed and data bits for this to work.
+
+A takeover request is only possible while the active console is
+showing the Boot Loader prompt prior to typing any characters at
+the active console.  In other words, once you start typing at the
+active console prompt, the takeover polling is suspended.  If you have
+started typing characters, you can press \<enter\> at the active
+console to get a fresh Boot Loader prompt and reactivate the polling.
+
+If you have built a custom ROM that includes an automatic boot
+command with a timeout, then performing a console takeover will
+abort the timeout process and the automatic boot command will not be
+performed.

Wayne Warthen	807999928e	Tweak Console Takeover Mechanism Based on input from Martin R, the console takeover mechanism has been modified to require that the space bar be pressed twice in a row on the character unit desiring to be the console. This reduces the chance of a spurious console takeover due to garbage input on serial ports.	2024-02-07 13:14:27 -08:00
Wayne Warthen	0b1bbf3d2b	Improve Propeller Font Lars Nelson has tweaked the special graphics characters on the Propeller so that the vertical bar character is better aligned with the other graphics characters.	2024-02-07 13:11:35 -08:00
Wayne Warthen	d93e639e4b	Added Console Takeover Mechanism - If enabled by AUTOCON config setting, you can press <space> at any character device to take over the console at the boot loader prompt. - Correction to SIOSEEK documentation in System Guide.
