<DIV><FONT face="Courier New" size="2">Does
this mean say a xPL OSD device (pic controlled) must also filter through
other things like ...x10.basic looking for TEXT tags ??? if so
how does a pic do it easily ?? Sorry for the dumb questions
?</FONT></DIV>
<DIV><FONT face="Courier New"

<DIV><FONT face="Courier New"
size="2">Nope. That tag is optional, so a given device doesn't
*have* to support it: obviously, the richer support a device can offer the
better..</FONT></DIV>
<DIV><FONT face="Courier New"

<DIV><FONT face="Courier New" size="2">In
the scheme documents on Tony's site, those elements with [ ] around them
are optional, so for OSD.BASIC, only the TEXT= is mandatory, everything
else is optional..</FONT></DIV>
<DIV><FONT face="Courier New"
size="2"></FONT> </DIV>
<DIV><FONT face="Courier New" size="2">One
thing to be aware of though: the *order* of tags is not arbitrary: if an
optional tag is present, it must be in the correct order, and any
*extended* entries must always appear after the *basic*
ones..</FONT></DIV>

<DIV><FONT face="Courier New" size="2">so,
in my OSD example:</FONT></DIV>

<DIV><FONT face="Courier New" size="2">If
my CID script wants to send a two line message and a ten second
delay...</FONT></DIV>
<DIV><FONT face="Courier New"
size="2"></FONT> </DIV>
<DIV><FONT face="Courier New"
size="2">TEXT= and DELAY= are part of OSD.BASIC, so come
first:</FONT></DIV>
<DIV><FONT face="Courier New"

<DIV><FONT face="Courier New"
size="2">TEXT=Line One of the Message</FONT></DIV>
<DIV><FONT face="Courier New"

wished to specify a foreground colour, in the message (using the current
