I have, I do not

the problem lies in the fact that a tty is inherently a 7bit device, and 
lacks the characters for line drawing.  many terminals can actually produce 
those characters, however, and this is accounted for in termcap/terminfo 
entries.  To get at them, use [w]addch(ACS_xxxx)
where the full list of ACS_xxxx values can be found in curs_addch(3)

You're specifically after
ACS_[HV]LINE		horizontal or vertical line
ACS_[UL][LR]CORNER	upper/lower left/right corner

so ACS_ULCORNER is the upper left corner character.

The neat thing about these defines is they're not constant values -- they 
change to something your terminal can support (usually +, - and |)
