Working on phantom channels

BRIZ supports work on phantom channels. For this purpose the mode of expectation of connection with a server is added. The server library contains programs for maintenance of establish of connection. The program of processing of events and all other programs of server library can work in usual and phantom modes. For the organization of the channel it is necessary:

• To start the terminal on the specified machine in a listening mode or to transfer the current session in a listening mode
• To execute program GPTerm.PHANTOMPRG having transferred it as parameter a name of the program and the address of the remote machine
• If necessary to finish the current session

At work on phantom channels the restrictions determined by absence of the terminal operate.

Description of GPTerm.PHANTOMPRG

format: EXECUTE "Z GPTerm.PHANTOMPRG PfItemName"

where PfItemName - item name in the pointer file.

Item structure:

a1 IP address or name
a2 listen PORT
a3 Programm to execute

Example:

psstr="127.0.0.1":@am:"1967":@am:"GPEDIT"
OPEN "PF" TO pf
WRITE psstr ON pf,"PS"
CLOSE(pf)
CALL GPTerm.LISTEN(1967,1000,"")
EXECUTE "Z GPTerm.PHANTOMPRG PS"
EXECUTE "EXIT"
