MTS 4: Terminals and Networks in MTS July 1988 where "n" is an integer from 0 to 8, and "string" may be any string of characters. For example, the following sequence of device commands will reconfigure the shifted program functions keys to transmit different device commands, MTS commands, and other replies to the system: %PFB0=%PAGE %PFB1=%LINE %PFB2=%ROLL %PFB3=%PF? %PFB4=$RUN *FORUM %PFB5=$MESS RETRIEVE NEW HEADER %PFB6=$CONTROL *PRINT* PRINTER=PAGE %PFB7=$RELEASE *PRINT* %PFB8=CANCEL Note that if the program-function string is to be used as a device command, that string must always be specified with an initial percent sign (%), even when the device-command character has been changed. The %PF? device command may be used to display the current status of all the program function strings. Note that whenever a program function key is pressed, if the string associated with that key is a valid nontransmitted device command, the line at which the cursor is positioned and the lateral position of the cursor are saved; that is, the line, including any undisplayed parts, is moved to the input area after the command is processed. If the cursor is in the input area when the PF key is pressed, the contents of the input area will remain unchanged. The cursor is also positioned so that its relative ________ lateral position remains unchanged. The ___________________________ FUNCTION Device Command Each key on the Ontel keyboard has a function code associated with it. When the key is pressed, the function code causes one of the following operations to occur: (1) A character or sequence of characters is inserted into the input area (e.g., pressing the SHIFT-A key inserts the character A into the input area). (2) A line-editing or terminal operation is performed (e.g., pressing the DELETE key deletes the character pointed to by the cursor and pressing the ATTN key generates an attention interrupt). (3) A character or sequence of characters is transmitted to the system (e.g., pressing the PF7 key transmits (by default) the %BLANK device command to the system). The %FUNCTION device command may be used to change the function code that is assigned to each key by default, thus allowing the user to 26 The Ontel Display Terminal
July 1988 MTS 4: Terminals and Networks in MTS redefine the operation of a key. The %FUNCTION command is given in the form %FUNCTION n m where "n" is the hexadecimal value used to identify the key being changed and "m" is the function code that is to be assigned to the key. Table 1 of Appendix B to this section lists the hexadecimal values used to identify each key along with the default function code that is associated with the key. Table 2 of Appendix B lists the definitions of the function codes. For example from Table 1, the unshifted PAUSE key is identified by the hexadecimal value E0 and has a default function code of 20. From Table 2, the function code 20 definition is "Enter/Exit Pause Mode". The shifted PAUSE key is identified by the hexadecimal value F0 and has the same default function code of 20. Hence, both the unshifted and shifted PAUSE keys have the same effect by default. The PAUSE key could be redefined by the user so that the shifted PAUSE key would have a different function code from the unshifted PAUSE key; for example, the shifted PAUSE key could be redefined to generate an attention interrupt by giving the command %FUNCTION F0 21 Note in Table 1 that the hexadecimal identifiers for CTRL-PAUSE and CTRL-SHIFT-PAUSE are the same as for PAUSE and SHIFT-PAUSE, respectively. This means that, for example, the PAUSE and CTRL-PAUSE keys cannot be assigned different function codes. Most of the keys in the function pad, the control pad, and the numeric pad are hardware designed so that the CTRL key will not produce a different function. The %FUNCTION command is most useful for redefining keys to use either program functions or define functions. Since there are 32 available program functions (PFA0-15 and PFB0-15) and only 18 combinations of program function keys (unshifted and shifted PF0-8), other keys must be used to access the other 14 program functions. By default, the program function keys use program functions PFA0-8 and PFB0-8. Also by default, the numeric keys in the standard keyboard are defined as program functions (PFA1-PFA12) when used with the CTRL key (e.g., CTRL-1 is defined as program function PFA1 and CTRL-0 is defined as PFA10). The following example illustrates how some of the numeric keys could be redefined to the program functions PFA9-15 and PFB9-15. %FUNCTION B1 89 (redefine CTRL-1 as PFA9) %FUNCTION B2 8A (redefine CTRL-2 as PFA10) ... %FUNCTION B7 8F (redefine CTRL-7 as PFA15) %FUNCTION C1 99 (redefine CTRL-SHIFT-1 as PFB9) %FUNCTION C2 9A (redefine CTRL-SHIFT-2 as PFB10) ... %FUNCTION C7 9F (redefine CTRL-SHIFT-7 as PFB15) The Ontel Display Terminal 27
