I
assume since you will be communicating non BSCEL since the sending system is not
an AS400. Basically, you config a line using CRTLINBSC. You must
also create a BSC controller and device. Be sure the lined is set up for
autoanswer *YES and the initial connection on the controller is set for
*ANS. when you compile your ICF file, you can specify the device name from
above in the Acquire device parameter on the CRTICFF command. If you do
not, you will need to issue an the acquire command in your RPG program or you
can specify the device name in the CL by using an OVRICFF command. You
must also use the ADDICFDEVE command to add an ICF device entry. Here you
can specify blocking, records lengths, block lengths. The code is really
petty simple, the program sits in a wait (read) of the ICF file. The call
comes in on the line, and the controller list is checked to see what controller
is associated with the line. It then looks up the device to see what ICF
file is associated with it. The ICF file is attached to the
program. You have to have the BSC receive program running at all
times. Create a SBS and create an autostart job that runs the receive
program. After you receive data, go back and wait for another
call.
Basically here is the hierarchy of
BSC.
LINE
Controller
Device
ICF file
RPG program
Physical file
If you
were communicating with a system that support BSCEL (BSC Equivalency link), I
believe you could actually EVOKE the remote program automatically, much like you
can do with SNA/APPC communications.
