Get
Tags
and Get Attributes to check the spelling of tag and attribute names.

displays error messages, but does not indicate which hot link command the
error references. To view the DDE Server window, return to the Windows
Program Manager window and select

If you attempt to open a 257th hot link (one more than the maximum
allowed), OSx returns an initial value to the client. However, the system
does not update the value, and the hot link is invalid. The @aGlance/IT
DDE Server window displays the following error message:
All available hot links in use.
If a hot link appears to have failed (values are no longer changing as
expected), do the following.
 Check the @aGlance/IT DDE Server window for error messages. Note
that if several values are changing rapidly for each active hot link,
error messages may have scrolled out of the window and beyond the
range of the scroll bar.
A network transport error (
Remote system error; Connect request
refused
) may indicate a network problem, such as pulled o r broken
cable at the client. This can cause the OSx @aGlance server to shut
down. Refer to Section 1.5 for help in restarting the server.
 Verify that the number of active hot links has not exceeded 256.
