A year or so ago I emailed these patches to the maintainer and didn't get any feedback. Just rediscovered them so figured I should submit them before they get lost... patch-bioscursor Fixes the BIOS cursor handling so that programs such as the DOS edit.com and qbasic.exe work correctly patch-desqview-timeslice Allows INT15 timeslicing so that programs which support it can avoid 100% CPU utilization patch-quitemode Adds a -Q option which suppresses all video IO. Also helps optimize the input behavior especially when polling for input. patch-fossil-support Adds a -F option which enables support for FOSSIL IO using stdio. PR: ports/114615 Submitted by: Stephen Hurd <shurd@sasktel.net> Approved by: maintainer timeout
