File: comm.c
Desc: This file implements the actual transmission portion
of the "ok to power me down" message to the remote
power cycling black box.
It's been sepatated into a separate file so that
it may be replaced by any other comm mechanism desired.
(including none or non serial mode at all)

Split the modbus comm part of the program (that sends the ok to pwr me down
message) into another file "comm.c"
#include <stdio.h>
#include <stdlib.h>
#include <unistd.h>
This is the routine that forms and
sends the "ok to pwr me down" message
to the remote power cycling "black box".
int do_pwr_dn(int fd, int cycleCnt)
char buf[200];
sprintf(buf, "ok to power me down!\nCount = %i\n", cycleCnt);
if(write(fd, buf, strlen(buf)) < strlen(buf))
perror("write error");
return -1;
return 0;
