you need to increment try each time through the loop.
this works for me:
#include <u.h>
#include <libc.h>

void
fu(void)
{
	int rd, try;
	char buf[1024];

	for(try=0; try < 2; try++){
		alarm(2 * 1000);
		rd = read(0, buf, 1024);
		alarm(0);
		if(rd > 0) {
			write(1, buf, rd);
			break;
		}
	}
}

void
main(void)
{
	fu();
	exits("");
}
