Hi,
I have downloaded rt_com module from
http://www-public.rz.uni-duesseldorf.de/~jochen/computer/software/rt_com/
, and I have compiled it, without any modifications, with:
gcc -I/usr/src/linux/include -Wall -Wstrict-prototypes -O2
-fomit-frame-pointer -fno-strength-reduce -D__RT__ -D__KERNEL__
-DMODULE -c -o $1.o $1.c
The compilation seems to be correct.
Later I use:
setserial /dev/ttyS1 port none
I run the module, insmod rt_com.
To test the correct functioning, I use a Linux system computer with a
null modem cable, in com2, on the other side there is a MsDos system
computer, the cable is in com1, this computer uses a simple serial
comunication program, it is configured with 9600 baud, 1 start bit,
8 data bits, 1 stop bit, and no parity.
To comunicate with, I run the following module:
#define MODULE
#include <linux/module.h>
#include <linux/cons.h>
#include <stdio.h>
#include "rt_com.h"
int init_module(void) {
char c1 [11] = "Hello world\0";
rt_com_setup( 1, 9600, RT_COM_PARITY_NONE, 1, 8); /* 1 = com2, */
rt_com_write( 1, c1, strlen(c1));
return 0;
}
void cleanup_module(void){
printk("Adi¢s, By, Chao, Ovuar, \n");
}
I wait, but the typical "Hello world" don't arrive to the Msdos computer.
I need a lot of examples of rt_com.
Help me, please.
