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 will be 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 a serial signal with

the string s, trimmed, through the signal i immediately upon receipt of the

message:

CTRL>Si=s

For example, the control equate

CTRL>S4= Wag the dog.

would send the serial string “Wag the dog.” through signal SignalS4 as soon as

the message is downloaded from the host.

Note that the string s is “trimmed” (leading and trailing spaces are removed) before

sending.
