Change zsh for MINGW session https://superuser.com/questions/961699/change-default-shell-on-msys2

sh -c "$(curl -fsSL https://raw.githubusercontent.com/ohmyzsh/ohmyzsh/master/tools/install.sh)"

Set in mingw64.ini:

SHELL=/usr/bin/zsh

There is no PTS on windows so use telnet instead

Add D:\msys64\mingw64\bin to PATH of Windows
Then telnet to attach to con1

telnet localhost 4321
