Dear Ralph

Thanks for the suggestion.

I read up om the BO record (I am running 3.15) using the HIGH field for the "Push bottom" behavior. 
As I understand that documentation, the record is processed again when going low after the specified time. 

I guess that will mean that the protocol is executed twice?  Any way to avoid that?
This brings back the problem that the response from the device depends on its current state
(it is different when going from On -> Off, and from Off -> Off).

A Simple push bottom that executes an protocol entry ones, will be very usefull for me. 

Best

I need to send one of the following commands:

SET SSTOP=1

or

SET SSTOP=0

However, the response is different in the two cases.

I think a "BO" record, should be used, but is there anyway I can have
different protocol definitions for the "1" and "0" state?

Alternatively, is there an easy way to separate this into two records?

I would just map the behaviour:

Create two protocols for on and off, with hardcoded values and command-specific replies.

Use two bo records, push-button style, HIGH=0.1, and connect them to the two protocols.

If you need a switch instead of two push-buttons, add another bo for the switch, FLNKing to a seq record in SELM=specified mode that writes a 1 to the appropriate push-button.

Cheers,
