Ok. This is indeed the result if you run the original LNP package. There
are several problems with your sources, too. So try the following to get
things done:
First, go to the lnpd subdir and edit rcxtty.c. In function tty_init you
find a line with:
ios.c_cflag = CREAD | ...
it should read:
ios.c_cflag = CREAD | CLOCAL | CS8 | (highspeed ? 0 : PARENB | PARODD);
You could take a look at the rcxtty.c file in the util/dll-src subdir of
brickOS, you will find the same initialization. This will wipe out the
frame errors. But your program won't run, anyway. You should change some
things so you will get:
PC PROGRAM:
===========================================================
#include <liblnp.h>
#include <stdio.h>
#include <stdlib.h>
#include <unistd.h>
#include <sys/time.h>
#include <sys/types.h>
#include <string.h>
#define MY_PORT 7
void addr_handler(const unsigned char* data,unsigned char length,
unsigned char src)
{
switch(data[0]) {
case 's':
printf( "%s\n", &data[1] );
break;
case 'i':
printf( "%d\n", data[1] * 256 + data[2] );
break;
default:
printf( "unknown type\n" );
}
fflush( stdout );
}
int main ( int argc, char **argv ) {
if ( lnp_init ( 0, 0, 0, 0, 0 ) ) {
perror ( "lnp_init" );
exit(1);
} else {
printf ( "init OK\n" );
}
lnp_addressing_set_handler (MY_PORT, addr_handler );
while ( 1 ) {
};
return 0;
}
----------------------------------------------------------
RCX PROGRAM:
==========================================================
#include <lnp.h>
#include <conio.h>
#include <string.h>
#include <lnp-logical.h>
#include <dkey.h>
#define MY_PORT 2
#define DEST_HOST 0x8
#define DEST_PORT 0x7
#define DEST_ADDR ( DEST_HOST << 4 | DEST_PORT )
unsigned char buf[3];
unsigned char len = 3;
void printInt(int i)
{
int result;
buf[0] = 'i';
memcpy(buf + 1, &i, 2);
result = lnp_addressing_write( buf, len, DEST_ADDR, MY_PORT);
}
wakeup_t prgmKeyCheck(wakeup_t data)
{
return dkey == KEY_PRGM;
}
int main ( int argc, char **argv )
{
int c=0;
lnp_logical_range ( 0 );
while( 1 ) {
if( prgmKeyCheck( 0 ) ) break;
printInt( c );
cputw( c++ );
msleep ( 200 );
}
cputs ( "done" );
return 0;
}
