The following requests are available: ** TIOCSETD int *ldisc change the line discipline: *** TTYDISC termios interactive line discipline *** TABLDISC tablet line discipline *** SLIPDISC serial IP line discipline *** PPPDISC PPP line discipline ** TIOCGETD int *ldisc return the current line discipline ** TIOCSBRK set the terminal into BREAK condition ** TIOCCBRK clear the terminal BREAK condition ** TIOCSDTR assert data terminal ready ** TIOCCDTR clear data terminal ready ** TIOCGPGRP int *tpgrp return the terminal's process group ** TIOCSPGRP int *tpgrp associate the terminal's process group ** TIOCGETA struct termios *term get the terminal's termios attributes ** TIOCSETA struct termios *term set the terminal's termios attributes ** TIOCSETAW struct termios *term set the termios attrs after any output completes ** TIOCSETAF struct termios *term after any output completes, clear input and set termios attrs ** TIOCOUTQ int *num current number of characters in the output queue ** TIOCSTI char *cp manually send a character to the terminal ** TIOCSTOP stop output (like typing ^S) ** TIOCSTART start output (like typing ^Q) ** TIOCSCTTY make this the controlling terminal for the process ** TIOCDRAIN wait until all output is drained ** TIOCEXCL set exclusive use on the terminal ** TIOCNXCL clear exclusive use of the terminal ** TIOCFLUSH int *what clear input/output if `what' has FREAD/FWRITE set ** TIOCGWINSZ struct winsize *ws get the winsize information ** TIOCSWINSZ struct winsize *ws set the winsize information ** TIOCCONS int *on redirect kernel console messages ** TIOCMSET int *state set the modem state bit flags according to the following: *** TIOCM_LE Line Enable *** TIOCM_DTR Data Terminal Ready *** TIOCM_RTS Request To Send *** TIOCM_ST Secondary Transmit *** TIOCM_SR Secondary Receive *** TIOCM_CTS Clear To Send *** TIOCM_CAR Carrier Detect *** TIOCM_CD Carrier Detect (synonym) *** TIOCM_RNG Ring Indication *** TIOCM_RI Ring Indication (synonym) *** TIOCM_DSR Data Set Ready ** TIOCMGET int *state get the modem state bit flags ** TIOCMBIS int *state add modem state bit flags, OR-ing in the new states ** TIOCMBIC int *state clear modem state bit flags The struct winsize *ws arguments use the winsize record: make-winsize free-winsize winsize-row winsize-col winsize-row-set! winsize-col-set! The struct termios *term arguments use the term-attrs record from the stty egg. The integer pointer arguments can be handled with pointers from the lolevel extension. == Author [[Alex Shinn]] == Repository This egg is hosted on the CHICKEN Subversion repository: [[https://anonymous@code.call-cc.org/svn/chicken-eggs/release/5/ioctl|https://anonymous@code.call-cc.org/svn/chicken-eggs/release/5/ioctl]] If you want to check out the source code repository of this egg and you are not familiar with Subversion, see [[/egg-svn-checkout|this page]]. == License BSD == History ; 0.3 : Ported to CHICKEN 5 Description of your changes:
