I am making a module that have to register a Line discipline. But i cant fugure out what to name it(what number do it get). When i look at the files mentiond below, i can't see how to introduce a new line discipline witout changing the kernel itself. linux/tty.h #define NR_LDISCS 16 asm/termios.h /* line disciplines */ #define N_TTY 0 #define N_SLIP 1 #define N_MOUSE 2 #define N_PPP 3 #define N_STRIP 4 #define N_AX25 5 #define N_X25 6 /* X.25 async */ #define N_6PACK 7 #define N_MASC 8 /* Reserved for Mobitex module <kaz@cafe.net> */ #define N_R3964 9 /* Reserved for Simatic R3964 module */ #define N_PROFIBUS_FDL 10 /* Reserved for Profibus <Dave@mvhi.com> */ #define N_IRDA 11 /* Linux IR - http://irda.sourceforge.net/ */ #define N_SMSBLOCK 12 /* SMS block mode - for talking to GSM data card #define N_HDLC 13 /* synchronous HDLC */ #define N_SYNC_PPP 14 /* synchronous PPP */ #define N_HCI 15 /* Bluetooth HCI UART */ /* here I asume i want to write #define N_MYDISC 16 */ drivers/char/tty_io.c int tty_register_ldisc(int disc, struct tty_ldisc *new_ldisc) { if (disc < N_TTY || disc >= NR_LDISCS) return -EINVAL; if (new_ldisc) { ldiscs[disc] = *new_ldisc; ldiscs[disc].flags |= LDISC_FLAG_DEFINED; ldiscs[disc].num = disc; } else memset(&ldiscs[disc], 0, sizeof(struct tty_ldisc)); return 0; } -- Martin Hansen Student at SDU Sønderborg. www.sdu.dk Writing final project at Danfoss drives. www.danfossdrives.com Tlf: 74 88 54 62 -- Kernelnewbies: Help each other learn about the Linux kernel.
