Description

MinTTY allows to change cursor styles and colors but mosh ignores them. This would be useful for vim (different insert and normal mode cursors)

Mode-dependent cursor in vim: CSI Ps SP q

Example: echo -ne '\e]12;#00FF00\a' # green cursor http://code.google.com/p/mintty/wiki/Tips#Mode-dependent_cursor_in_vim

Changing colors: OSC Ps ; Pt ST OSC Ps ; Pt BEL

Example: echo -ne "\e[2 q" # non blinking block cursor http://code.google.com/p/mintty/wiki/Tips#Changing_colours
