Summary

AI summary

Write() now sends carriage return (\r) for Enter key to fix telnet/BBS command execution.

Full changelog

Bug Fixes

  • \r for Enter key — Write() now sends \r (carriage return) instead of \n. Fixes telnet/BBS commands not executing (telehack cowsay, PTT login).
  • AdvanceMarkBy race fix — ReadScreen advances mark by exact bytes consumed, preventing data loss between WaitForSettle and Mark.
  • WaitForSettle empty settle fix — No longer settles on empty output after 300ms.
  • wait_for stale data fix — Pattern matching only scans unread output.

Verified With

  • Telehack: cowsay, joke, figlet all return complete output
  • PTT BBS: login prompt works correctly
  • Local bash: echo, sleep, ping all behave as expected
