Bug in 88.5

        if (pollret>0) {
  	int readct;
! 	char buf[30];
  	/* Have input */
! 	readct = read(inputfd,buf,30);
  	if (readct==0) {
  	  fprintf(stderr,"Bletchdie\n");
  	  exit(-1);
  	}
! 	if (readct>20) {
  	  fprintf(stderr,"Error, Protocol Violation, input too long");
  	  exit(-1);
  	}

        }
        if (pollret>0) {
  	int readct;
! 	char buf[50];
  	/* Have input */
! 	readct = read(inputfd,buf,40);
  	if (readct==0) {
  	  fprintf(stderr,"Bletchdie\n");
  	  exit(-1);
  	}
! 	if (readct>39) {
  	  fprintf(stderr,"Error, Protocol Violation, input too long");
  	  exit(-1);
  	}
