1. Starting up the screens and the observing program.
This describes how to start up from scratch. If some screens are running, see section 2 on how to shut
them down.
2. Shutting down the observing program and the screens.
3. Details on starting up the screens.
To start up the screens without using "gbimenu" script, or if you want
to bring up one or more of them separately:
4. Setting up for observing.
After you have all the screens set up and arranged nicely,
its time to check the clock and start the observations.
5. Dealing with Problems.
Before you delete the lock file, make sure the User Control screen really
is not running!
To check, do "ps -ef" and look for the string: "glish -l gbarray.g 853",
or "glishgc -l gbarray.g 853".
To delete the lock file for 85-3:
Files in these directories are named with the date (or date and time)
when they were first created. You can look through these files with
"more", "less", or an editor.
The other possibility is that some of the YGOR demons on osiris are
not running. If status.853 or T85status.html are not updating,
you can use TaskMaster to stop and re-start "statwebgbi".
The more drastic solution is to re-boot osiris.
For more about TaskMaster and the YGOR demons,
refer to section 4 of
"software and computer setup".
6. Brief introduction to YGOR managers.
7. Brief introduction to 85-foot Antenna Managers.
Some comments on manager commands "stop" and "abort".
Another comment: whenever you change from the "AUTO" to the "MAN" command mode, a
manager "stop" will happen. That means that the manager will go to the "Ready" state
whenever you change to "MAN" mode, and it may go into the "halt" obs mode, depending on
what it is doing.
8. Direct commands to the single-board computer.
This describes commands you can type to the single-board computer (either "gb853" for 85-3 control,
or "gbint" for 85-1 and 85-2).
To do this, you must type in the "gb853_vxworks" window. This is the window that is
running "minicom" and communicating with the "gb853" single-board computer.
For the GBI, use the minicom window for "gbint".
In this window, you will see the "->" cursor.
You can view a brief help message by typing: T85help
Note that the antenna number "ant", for the 85-3 manager, must be given as "1",
not "3" !
Some examples, for 85-3.
this brings up 2 screens:
If the gb853 needs to be rebooted,
type "reboot" in this window.
This brings up a small green window:
Check to make sure the default configuration is chosen, then click "ok"

T85 commands you can give from the vxWorks shell:
estop -- stop all antennas instantly
astop -- stop all antennas, nicely
onstat ant -- print status for antenna
(ant = 1, 2, or 3)
offstat ant -- turn off the printing
ff -- turn off printing for all
setmode mode,ant -- set Obs mode for ant
mode is number 0-16; ant is antenna# 1-3
mode = 0,1 to force manual,auto ctlmode
