Mark was starting cygwin using the cygwin.bat script. This results in a terminal with /dev/cons0 (or cons1, cons2, etc) instead of /dev/ptyX as the tty. From the cygwin documentation:
> Starting with Cygwin 1.7.10, Console sessions are numbered from /dev/cons0 > upwards. > Console device names are pseudo device names, only accessible from processes > within > this very console session. This is due to a restriction in Windows. So it appears that Windows prevents the tmux server from gaining access to the consX device, and this prevents tmux from working. Using mintty or rxvt to get the cygwin window will allow tmux to work since they use pty devices. ------------------------------------------------------------------------------ Learn the latest--Visual Studio 2012, SharePoint 2013, SQL 2012, more!
