Key binding

Depending on the hardware configuration, and your keyboard configuration, the serial interface may have a special key binding:

F1   is   <ESC>1 
F2   is   <ESC>2 
F3   is   <ESC>3 
F4   is   <ESC>4 
F5   is   <ESC>5 
F6   is   <ESC>6 
F7   is    <ESC>7 
F8   is   <ESC>8 
F9   is   <ESC>9 
F10  is   <ESC>0 
F11  is   <ESC>! 
F12  is   <ESC>@

Home    is <ESC>h 
End     is <ESC>k 
PageUp  is <ESC>? 
PageDn  is <ESC>/
Insert  is <ESC>+ 
Delete  is <ESC>- 

<Ctrl><M> is <ESC><Ctrl><M> 
<Ctrl><H> is <ESC><Ctrl><H>
<Ctrl> is <ESC><Ctrl>
<Ctrl><J> is <ESC><Ctrl><J>

Also, use the <ESC><X><X> key sequence for <Alt><x>, where x is any letter key, and X is the upper case of that key
