- Subject: [PATCH] Cygwin: pty: Fix ESC[?3h and ESC[?3l handling again.
- Dkim-filter: OpenDKIM Filter v2.10.3 conuserg-03.nifty.com xBJB3cw1004269
- Even with commit fe512b2b12a2cea8393d14f038dc3914b1bf3f60, pty
still has a problem in ESC[?3h and ESC[?3l handling if invalid
sequence such as ESC[?$ is sent. This patch fixes the issue.
