AVAILABILITY SPARC

DESCRIPTION The kb STREAMS module processes byte streams generated by keyboard attached to a

CPU serial port. Deﬁnitions for altering keyboard translation, and reading events from

the keyboard, are in <sys/kbio.h> and <sys/kbd.h>.

kb recognizes which keys have been typed usinga set of tables for each known type of

keyboard. Each translation table is an array of 128 16-bit words (unsigned shorts). If an

entry in the table is less than 0x100, it is treated as an ISO 8859/1 character. Higher values

indicate special characters that invoke more complicated actions.

Keyboard

Translation Mode

The keyboard can be in one of the following translation modes:

TR_NONE Keyboard translation is turned off and up/down key

codes are reported.

TR_ASCII ISO 8859/1 codes are reported.

TR_EVENT ﬁrm_events are reported.

TR_UNTRANS_EVENT ﬁrm_events containing unencoded keystation codes

are reported for all input events within the window

system.
