==Relay for pump==
In Houston we installed a relay that allows us to remotely turn on and off the power to the gantry. There are scripts in the <code>COM</code> directory called <code>RELAY_PUMP_...</code>.

Install the special <code>TELNET_CLIENT.EXE</code> as user <code>system</code> into <code>DISK0:[SYS0.SYSCOMMON.SYSEXE]</code> so that it is accessible and then set the permissions:

 $ set def disk0:[sys0.syscommon.sysexe]
 $ set prot=(s:rwed,o:rwed,g:re,w:re) telnet_client.exe

You need to set a logical (can be set permanently in <code>LOGIN.COM</code>):

 $ DEFINE TELNET_SERVER_LINE "TCPIP$DEVICE:172.16.1.2:9500"

Then you can turn the gantry on or off with

 $ mcr telnet_client -on
 $ mcr telnet_client -off

And you can check the current status of the gantry by pinging it:

 $ TCPIP PING 192.168.34.18

The output for when the gantry is <code>on</code> looks like this:

  $ TCPIP PING 192.168.34.18
  PING 192.168.34.18 (192.168.34.18): 56 data bytes

And when it is <code>off</code> it looks like this:

  $ TCPIP PING 192.168.34.18
  PING 192.168.34.18 (192.168.34.18): 56 data bytes

There is a script called <code>RELAY_PUMP_10_MIN_ON.COM</code> that self-submits and automatically turns on and off the gantry on Sunday at 2am.
