Definitions for altering keyboard translation and reading events from the keyboard are contained in <\fBsys/kbio.h\fR> and <\fBsys/kbd.h\fR>. .sp .LP The \fBkb\fR STREAMS module utilizes a set of keyboard tables to recognize which keys have been typed. Each translation table is an array of 128 16-bit words (\fBunsigned short\fRs). If a table entry is less than 0x100, the entry is treated as an \fBISO\fR 8859/1 character. Higher values indicate special characters that invoke more complicated actions. .SS "Keyboard Translation Mode" .sp .LP The keyboard can be in one of the following translation modes: .sp .ne 2 .mk .na \fB\fBTR_NONE\fR \fR .ad .RS 21n .rt Keyboard translation is turned off and up/down key codes are reported. .RE .sp .ne 2 .mk .na \fB\fBTR_ASCII\fR \fR .ad .RS 21n .rt \fBISO\fR 8859/1 codes are reported. .RE .sp .ne 2 .mk .na \fB\fBTR_EVENT\fR \fR .ad .RS 21n .rt \fBfirm_events\fR are reported. .RE .sp .ne 2 .mk .na \fB\fBTR_UNTRANS_EVENT\fR \fR .ad .RS 21n .rt \fBfirm_events\fR containing unencoded keystation codes are reported for all input events within the window system. .RE .SS "Keyboard Translation-Table Entries" .sp .LP All instances of the \fBkb\fR module share seven translation tables that convert raw keystation codes to event values. The tables are: .sp .ne 2 .mk .na \fBUnshifted\fR .ad .RS 14n .rt Used when a key is depressed and no shifts are in effect. .RE .sp .ne 2 .mk .na \fBShifted\fR .ad .RS 14n .rt Used when a key is depressed and a Shift key is held down. .RE .sp .ne 2 .mk .na \fBCaps Lock\fR .ad .RS 14n .rt Used when a key is depressed and Caps Lock is in effect. .RE .sp .ne 2 .mk .na \fBAlt Graph\fR .ad .RS 14n .rt Used when a key is depressed and the Alt Graph key is held down. .RE .sp .ne 2 .mk .na \fBNum Lock\fR .ad .RS 14n .rt Used when a key is depressed and Num Lock is in effect. .RE .sp .ne 2 .mk .na \fBControlled\fR .ad .RS 14n .rt Used when a key is depressed and the Control key is held down. (Regardless of whether a Shift key or the Alt Graph is being held down, or whether Caps Lock or Num Lock is in effect). .RE .sp .ne 2 .mk .na \fBKey Up\fR .ad .RS 14n .rt Used when a key is released. .RE .sp .LP Each key on the keyboard has a \fBkey station\fR code that represents a number from 0 to 127. The number is used as an index into the translation table that is currently in effect. If the corresponding entry in the translation table is a value from 0 to 255, the value is treated as an \fBISO\fR 8859/1 character, and the character is the result of the translation. .sp .LP If the entry in the translation table is higher than 255, it is a special entry. Special entry values are classified according to the value of the high-order bits. The high-order value for each class is defined as a constant, as shown below. When added to the constant, the value of the low-order bits distinguish between keys within each class: .sp .ne 2 .mk .na \fBSHIFTKEYS 0x100 \fR .ad .RS 20n .rt A shift key. The value of the particular shift key is added to determine which shift mask to apply: .sp .ne 2 .mk .na \fB\fBCAPSLOCK 0\fR \fR .ad .RS 17n .rt Caps Lock key. .RE .sp .ne 2 .mk .na \fB\fBSHIFTLOCK 1\fR \fR .ad .RS 17n .rt "Shift Lock" key. .RE .sp .ne 2 .mk .na \fB\fBLEFTSHIFT 2\fR \fR .ad .RS 17n .rt Left-hand Shift key. .RE .sp .ne 2 .mk .na \fB\fBRIGHTSHIFT 3\fR \fR .ad .RS 17n .rt Right-hand Shift key. .RE .sp .ne 2 .mk .na \fB\fBLEFTCTRL 4\fR \fR .ad .RS 17n .rt Left-hand (or only) Control key. .RE .sp .ne 2 .mk .na \fB\fBRIGHTCTRL 5\fR \fR .ad .RS 17n .rt Right-hand Control key. .RE .sp .ne 2 .mk .na \fB\fBALTGRAPH 9\fR \fR .ad .RS 17n .rt Alt Graph key. .RE .sp .ne 2 .mk .na \fB\fBALT 10\fR \fR .ad .RS 17n .rt Alternate or Alt key. .RE .sp .ne 2 .mk .na \fB\fBNUMLOCK 11\fR \fR .ad .RS 17n .rt Num Lock key. .RE .RE .sp .ne 2 .mk .na \fB\fBBUCKYBITS 0x200\fR \fR .ad .RS 20n .rt Used to toggle mode-key-up/down status without altering the value of an accompanying \fBISO\fR 8859/1 character.

The keyboard abort sequence effect (typically L1-A or Stop-A on the keyboard on SPARC systems, F1-A on x86 systems, and BREAK on the serial console device) is enabled if the \fBint\fR has a value of KIOCABORTENABLE(1). If the value is KIOCABORTDISABLE(0) , the keyboard abort sequence effect is disabled. If the value is KIOCABORTALTERNATE(2), the Alternate Break sequence is in effect and is defined by the serial console drivers \fBzs\fR(7D)\fBse\fR(7D) and \fBasy\fR(7D). Any other value of the parameter for this \fBioctl()\fR is treated as \fBenable\fR. The Alternate Break sequence is applicable to the serial console devices only. .sp Due to a risk of incorrect sequence interpretation, SLIP and certain other binary protocols should not be run over the serial console port when Alternate Break sequence is in effect. Although PPP is a binary protocol, it is able to avoid these sequences using the ACCM feature in \fIRFC 1662\fR. For Solaris PPP 4.0, you do this by adding the following line to the \fB/etc/ppp/options\fR file (or other configuration files used for the connection; see \fBpppd\fR(1M) for details): .sp .in +2 .nf asyncmap 0x00002000 .fi .in -2 SLIP has no comparable capability, and must not be used if the Alternate Break sequence is in use. .sp This \fBioctl()\fR will be active and retain state even if there is no physical keyboard in the system. The default effect (\fBenable\fR) causes the operating system to suspend and enter the kernel debugger (if present) or the system prom (on most systems with OpenBoot proms). The default effect is enabled on most systems, but may be different on server systems with key switches in the 'secure' position. On these systems, the effect is always disabled when the key switch is in the 'secure' position.
