User's Manual

You can also make devices that are allocated to a remote area available through the
DEV_Ras_Area_b value in the eKERNEL_DEVICE table. An example is shown in Figure 145:

As a result, the SMTP server is contacted, and a message is sent. The IP address and port
number is retrieved for the server defined in the eSMTP_CLIENT table, with a matching site
and area as used by the Apache Web Server.
The mail is sent following the specs of RFC821. In the composed mail, the MAIL FROM:
keyword is automatically retrieved from the definition in the eWEB_USER_AUTH table. As a
result, when the destination user replies to the mail, the reply arrives in the correct mailbox of
the sender.
Send Server Message
Send Server Message is a function that communicates to the eKERNEL module.
This is the opposite of the Send DMS-API Message and Send SMTP Message, both of which
directly access the underlying services and ignore the eKERNEL module for processing. A
major advantage of using Send Server Message is that it utilizes more product features,
including: logging, sending to a group of users, assigning alarm types, priorities, addressing
any kind of peripherals, implementing confirmation procedures, implementing alternatives
devices, and so on.
Because Send Server Message communicates with eKERNEL, a number of configuration
actions are required. One of them is specifying alarm identifiers in the eKERNEL_ALARM
table, for the input program that is assigned to the eWEB instance. At this time, you can define
for instance alarm types with different lengths (for example, short messages of 8 bytes, medium
messages of 16 bytes and long messages of 32 bytes).
Important:
Because the Send Server Message is designed only to set a message, and cannot reset a
message, you must always specify remove after *SENT in the eKERNEL_ALARM table,
otherwise the message remains active forever.
