Connecting via TN3270E...

[perrone]

Hi,

Does anybody know or already worked(programming) with systems that are hosted on Mainframe? I have one problem... there are data that are stored in old database like ADABAS. The only way that i have access to this data is through terminals (3270). My question is:"Is there way via programming(PHP's script) that i can simulating one terminal/3270 and open one connection with Mainframe to capture data that are sent?" Today, i use the Attachmate's connectivity solution...but i'm developing an intranet application and this solution is not applied.

Thanks a lot

socket functions per chance?

The trick though is sending your packets in the correct byte-order so your server can read them and I suspect it's big-endian if it's an old legacy system.
...which could be a real big pain in the ass to work with since your scripts will write out little-endian packets.
So you'll have to do some hefty bitmasking to get it all to work... and I am so not envying you right now my man.

But, If I were you I would start just by opening a socket and grabbing the initial response and seeing if you could make it intelligible and work it from there.
