Revision history for Perl extension IO::Stty

0.05 Wed Mar 19 2026

  Bug fixes:
   - Fix broken single-arg baud rate setting. Passing a numeric rate like
     "9600" as the sole argument now correctly sets both ispeed and ospeed.
     The single-arg code path had two independent if/else blocks instead of
     one if/elsif chain, so the baud rate was silently never applied. (PR #11)
   - Replace unsafe symbolic dereference &{"POSIX::B" . $input} in the
     ospeed/ispeed handlers with a static %BAUD_RATES hash lookup. The old
     pattern was dead code in all public releases (use strict prevented it
     from running) but is now properly fixed. Unknown rates produce a
     warning instead of dying. (PR #7, PR #11)

  Improvements:
   - Add modern baud rates B57600, B115200, and B230400 with eval guards
     for platforms that lack them. (PR #9)
   - Render control characters in hat notation (e.g. ^C, ^D) in -a
     output instead of raw numeric values. (PR #8)
   - Add special character value parsing for stty(): accept hat notation
     (^C), hexadecimal (0x03), octal (003), decimal, and single literal
     characters when setting control char values. (PR #6)

  Maintenance:
   - Add functional pty-based test suite using IO::Pty covering flag
     toggling, -g/-a roundtrips, raw/cooked/sane modes, baud rate setting,
     and control character assignment. (PR #10)
   - Add baud rate regression tests with a decoy-function guard against
     reintroduction of symbolic dereference. (PR #7)
   - Modernize CI: replace three separate workflow files with unified
     testsuite.yml using current GitHub Actions. (GH #12, PR #13)
   - Update stale GitHub URLs (http to https) and modernize CPAN metadata
     to META spec v2 with TEST_REQUIRES. (PR #14)
   - Add cpanfile for CI dependency management.
   - Re-generate README from Stty.pm.
   - Apply Perl::Tidy formatting.
