Public bug reported: There are at least two older operating systems, being FreeBSD 2.2 and FreeDOS 1.2, that misbehave when the change command is used on the IDE CD drive, and work fine on a real machine. In both cases, changing the CD causes the guest to either refuse to read the disc or appear

[Bug 1895363] [NEW] borland IDEs double up cursor key presses (need timing on PS2 port input)

2020-09-11 Thread Michael Slade
Public bug reported: Most DOS-era IDEs from Borland (I have tried Borland C++ 2.0, Borland C++ 3.1 and Turbo Pascal 7.1) exhibit strange responses to the keyboard. Cursor keys are registered twice, so each press of a cursor key causes the cursor to move twice. Also the other keys occasionally are

Public bug reported: I *believe* (not confirmed) that the old standard PC serial ports, when configured with a character size of 7 bits or less, should set non-data bits to 0 when the CPU reads received chars from the read register. qemu doesn't do this. Windows 1.01 will not make use of a serial
