[wish-info] c script problem.

I am trying to create a c program that write a "1" on a x10 device, but
I cant. I run the program and it don't obtain any result: the device
don't turn on. But with a "echo 1 > /dev/x10/a2" it turn on.
This is the code:

const char* cadena = "1";
int i, currentstatus;

fd = open("/dev/x10/a1",O_WRONLY);

if (!(fd))
printf("No pude abrir");
else
printf("El fd es %i", fd);

write(fd, cadena, strlen(cadena));
close(fd);

Can you help me?

Thanks

I solved it sending "100". I tested it with a c script and a php script
and runs ok.

Thanks.

Sending 100? That shouldn't work. What this means is that I have an old
bug back in the parser. A year ago I had a bu where the parser would
truncate the last character because "echo" sends a carriage return on the
end of every command. But when you do it from a C program, you often do not
send the carriage return.

I need to look through the code. I am assuming that this is the 2.0.0 code?

No! It is the 1.6.10 version. I am using it until you solve the problem
for compile it on my motherboard.

I tested sending "1\n" and it runs OK.

Thanks.
