The message text will be displayed on the Equipment's CRT. Collection Event S10Ack (CEID 12) occurs once the
operator has acknowledged the message and an Event Report will be sent to the Host (if enabled).
The S10F3 and S10F9 are restricted to a single TEXT data item, but S10F5 can contain multiple TEXT data items. Each
TEXT data item is limited to 160 characters. Each data item in S10F5 will be displayed on a separate line at the
equipment.
If the Operator has not acknowledged an existing message when the Host sends another message, the new message will be
displayed and the old one discarded.
The Host can send a message with a 0-length text to clear the Operator text display.
Also, the Equipment allows the operator to send a single block message to the Host via S10F1. The maximum length of
this text is 160 characters. The S10F2 response from the Host is ignored.
