✨ b3270 — the IBM host access tool back end ✨

okay bestie, gather round, because this is the back end of the whole operation and she is lowkey carrying the entire group project 💅

It's a page from the General Commands Manual, section 1, and her name is literally just b3270. Iconic. No notes.

🌸 SYNOPSIS 🌸

Two ways to pull up, pick your fighter:

b3270 [options]
b3270 [options] session-file.b3270

yeah that's it. options first if you want them, then optionally a session file. simple. clean. slay.

🦋 DESCRIPTION 🦋

so here's the vibe: b3270 opens a telnet connection to an IBM host, and while it's there it handles the 3270, TELNET and TLS protocols — like, all three, no big deal, she's just built different 🫶

The twist is that she does not do the user-interaction thing herself. Nope. She hands all of that off to a front-end application, because she's the back end and she knows her role. main character energy, but make it infrastructure 💅

How do they talk? Through XML ✨ — on her standard input and her standard output. That's the whole communication channel between the back end and the front end. it's giving pen pals, it's giving passing notes in class, it's giving XML.

And the receipts, because she is fr fr legit:

  • She implements RFC 2355 — that's TN3270E, bestie
  • She implements RFC 1576 — that's TN3270
  • She implements RFC 1646 — that's LU name selection
  • And she supports IND$FILE file transfer 🔥

not her being a whole protocol queen 😭
