Definition of these signals is optional. The number of signals defined is controlled
by the value in the A textbox in the e-Mail control message signals frame of the
e-Mailbox Signal Block Definition window. A zero (0) in this box means that no
SignalA signals are defined at all.
A message with the following “control equate” syntactical construct in the subject
header or in any line of the body text causes the server to send an analog signal
with the state d through the signal i immediately upon receipt of the message:
CTRL>Di=d
For example, the control equate
CTRL>D2=true
would send an assert through signal SignalD2 as soon as the message is
downloaded from the host.
Note the syntax for d is case-insensitive and the following values are permitted:
Assert Deassert or de-assert
True False
On Off
1 0
Yes No
Set Reset
Ok or Okay Cancel
