Sending Messages From the Host
Table 8-1 lists the possible combinations of terminal names, alias names, and alias
types, and which workstation applications receive messages. An asterisk (*) indicates
all terminals or all aliases.
Sending Messages From the Host
To send unsolicited messages, host applications open the TDP process, using the
Guardian OPEN procedure, and write unsolicited messages, using the WRITE or
WRITEREAD procedure. See the Guardian Procedure Calls Reference Manual for
more information about these procedures.
The host application places the terminal name, alias name, and alias type, identifying
the unsolicited message recipients, in a header at the beginning of the message buffer.
