Here is some information about Motorola's EXORterm 155 and EXORterm 200.
Here is a picture of an EXORterm: http://digitaltmuseum.no/011015371771/motorola-datamaskin-exorciser-exorterm-exordisk
The EXORterm 155 is a CRT-based display console designed to work with the EXORciser:
* 12 inch screen
* 80 column x 24 line display
* 128 character font
* 96 ASCII characters
* 24 lower case Greek characters
* 2 uppercase Greek characers and 6 special characters
* RS-232C and 20/60 mA current loop interface
* Up to 9600 BAUD
* Support for 193 and 202 modem controls (support for half duplex)
The EXORterm 155 does not support the DEC VT100 / ANSI control sequences. Instead it has its own control language. It supports "page mode", which many terminals of its era had (inspired by IBM's 3270).
The EXORterm 200 is just like the EXORterm 155 but it has a small EXORciser development system built in. It has a card cage in the back which accepts EXORciser 86-pin boards.
These keys are on the keyboard (in addition to the usual ASCII keys):
| Key | Code or Function |

| ALL CAPS (with light) | (Force all caps) |
| AUTO LF (with light) | (Automatically line feed after carriage return) |
| ON LINE (with light) | (Switch between on line and local modes) |
| PAGE MODE (with light) | (Switch between page and scroll modes) |
| LF | 0x0A |
| ESC | 0x1B |
| BREAK | 300 ms "space" condition |
| RETURN | 0x0D |
| HOME (shift CLEAR) * | CLEAR=0xD8, HOME=0xC0. Allowed in scroll mode. |

(*) I'm fairly sure that these keys never send codes to the application. They edit the terminal screen only (and then only in page or protected mode, except where noted).
Page rollover: it means that when you try to move the cursor down when it's on the last line, it moves to the first line. Also, if you try to move the cursor up while it's on the first line, it moves to the last line.
Line and page rollover: it means when you try to move the cursor right when it's on the last column, it moves to the first column of the next line. If the cursor was on the last line, it's moved to the first line. Also, if you try to move the cursor left while it's on the first column, it's moved to the last column of the previous line. If the cursor was on the first line, it's moved to the last line.
Cursor position codes:
line/column 0: space / 0x20 line/column 1: ! / 0x21 line/column 2: " / 0x22 ... line/column 79: o / 0x6F
Some commands require both a line and column number. For these commands the line number is provided first:
command line column
Scroll mode: This is the normal mode of the terminal and it operates as you would expect: keyboard codes are sent directly to the application and the terminal scrolls the screen when it receives linefeed when the cursor is on the last line. There are very few screen editing commands available in this mode. There is no page or line rollover.
Page mode: There is page and line rollover. There is no scrolling (linefeed acts as cursor down with rollover). The terminal has built-in editing so that the keyboard can be used to edit the contents of the screen. You hit the page send or line send keys to transmit the screen or line contents to the application (also the application can send commands for page send and line send). Many editing commands become available.
Protect mode: This is just like page mode, except that certain fields can be set up to be protected from editing. The cursor is not allowed to appear in protected fields (it jumps over them). FAC (field attribute codes / AKA "magic cookies") are used to delineate the protected fields.
Screen locations can have magic cookies which set or reset display attributes. When a location has a magic cookie, it appears blank on the screen. If you overwrite the location with the magic cookie with a normal character, the attribute settings are deleted. On the other hand, the codes to set attributes do not quite act like characters: they do overwrite the character in the location (changing it to a space), but they do not cause the cursor to move. Also several attributes can be placed into the same character location. Once the attributes have been set, move off the location by issuing a cursor movement command, not by sending a space.
Attributes do not cross lines: they are reset to their defaults after each line.
0xE0 or ESC ` set blink
0xE1 or ESC a reset blink
0xE2 or ESC b set inverse
0xE3 or ESC c reset inverse
0xE4 or ESC d set dim
0xE5 or ESC e reset dim
0xE6 or ESC f set underline
0xE7 or ESC g reset underline
0xE8 or ESC h set non-display
0xE9 or ESC i reset non-display
0xEA or ESC j set field protect
0xEB or ESC k reset field protect
This mode is for support of the EXORmacs M68000 CRT Editor, the M6800 EXORciser resident editor does not need it.
If the CRT editor mode is enabled, the CRT enters a pseudo half-duplex mode requiring no echo from the host, and performs certain text editing functions. Optionally, the terminal notifies the host system when the cursor has been moved off the current line. If the current line has changes, the new data is always transmitted as part of a message packet.
All data and command message packets sent by the terminal cause the keyboard to be locked. The host needs to send an unlock command. BREAK key will also unlock.
