From c56b6209189f6a4945562dc772cff440f03e4868 Mon Sep 17 00:00:00 2001 From: Sven Schnelle Date: Fri, 20 Dec 2019 22:15:09 +0100 Subject: ps2: accept 'Set Key Make and Break' commands HP-UX sends both the 'Set key make and break (0xfc) and 'Set all key typematic make and break' (0xfa). QEMU response with 'Resend' as it doesn't handle these commands. HP-UX than reports an PS/2 max retransmission exceeded error. Add these commands and just reply with ACK.
