Mark,

Thank you for clarifying this.

However, I have a question I hope you can help with...  In your prior
message you say,

*   18) The SERIAL-API & DDE-API have been changed as follows:

a) For MONITORED Items, ECS will now send an update packet EVERY
   time the State of such Items are set to a value differing from
   the current. Previously, updates would be sent only once per pass,
   and so multiple State changes made during one Event-pass could
   be missed.
   WARNING: We recommend that you do NOT perform "intermediate"
   calculations on monitored Items, as every change will trigger
   a packet transmission (which could "flood" the Client).




I understand part a)     but have absolutely no idea what you're talking
about in part b)...

Could you clarify ???

        b) When a DDE client issues an Item State-change request
(SET/ADD/etc),
   ECS now returns the CURRENT (PRE-modified) State in the response
   packet (rather than the post-modified State). If the Item is
   MONITORED, a subsequent update packet will be sent when the
   State is modified. Note that for GROUP-MINIMUM/MAXIMUM Items,
   multiples may be sent.

Thanks,
