IBM 3270 PC. The basic 3270 extended data stream is pretty straightforward, although it gets more complicated for things kije file transfer and graphics.

I have a copy somewhere. But yeah, they've made it hard to grok. WSF is well documented in the 3270 protocol books-but those are probably hard to find these days. And 3270 programming in general isn't for the faint of heart. If I were [more?] evil and wanted to exfiltrate data on a system where IND$FILE was disabled/removed, I'd do as others have suggested: convert the data to hex nibbles and drive the screen using a script. Slow but doable. ...phsiii ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to [email protected] with the message: INFO IBM-MAIN ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to [email protected] with the message: INFO IBM-MAIN
