iSeries credit card approval interface

We currently send/receive credit approvals via an ICF file and SDLC line sent through a router. We must change this and our merchant services provider gave us software that runs on a PC and will monitor a port for data from the iSeries. How do I send the data to the port? Can I still use the ICF file? I know very little about communications and I'm not sure where to start. Thank you!

    is it a s/ware? if it is in the same network you will be able to monitor it. unless there is a firewall before as400 then u need to open the firewall port and allow the pc ip to monitor the port

    If you tell me the port they are monitoring I can tell you if it is a standard defined port or application defined. And, this sounds a little off because a listener program can really on "monitor" a port on a system where it, the listener program, is running. So if they want you to send data to a specific port on their Windows PC, your application on the i has to send to that port. If you are FTP of SFTPing(hopefully) your source port will be system defined and you can define the target port in the FTP script.

    ...runs on a PC and will monitor a port for data from the iSeries. How do I send the data to the port? In that case, you will most likely need to create programming that opens a socket to that port and uses the send()--Send Data or the write()--Write to Descriptor API to send each "message". You would then receive replies through that socket with the recv()--Receive Data or the read()--Read from Descriptor API. The Scott Klement RPG IV Sockets Tutorial is an excellent starting point. Can I still use the ICF file? Only the PC app provider can say for certain. But I wouldn't even take the time to ask because the answer is most likely "no" and because you're likely to need the sockets information anyway. The PC app provider has apparently given "monitor a port" as the preferred (and probably sole) method. While they might be able to provide similar capability via an ICF interface, it's just too unlikely to consider. Tom
