Re: string "no alarm" color in edm textupdate, text monitor behavior seems to vary

Carl,

Before edm, I was using the VSystem display manager which handled the 
"no alarm"
condition in a different manner than the EPICS display managers. As a 
result, I included
support for both behaviors. This is configured in the color file.

The following

alarm {
 disconnected : "white"
 invalid      : "med gold"
 minor        : "yellow"
 major        : "red"
 noalarm      : *
}

makes the "no alarm" color the color specified by the user.

Replacing the "*" with some color name, as in

alarm {
 disconnected : "white"
 invalid      : "med gold"
 minor        : "yellow"
 major        : "red"
 noalarm      : "green"
}

makes the "no alarm" color a fixed value.
