# I'm dreaming of an ascii character-based monochrome Christmas,
# Just like the ones I used to know!
# Via a full duplex communications channel,
# At 9600 bits per second,
# Even though it's kinda slow.
#
# I'm dreaming of an ascii character-based monochrome Christmas,
# With ev'ry C program I write!
# May your screen be merry and bright!
# And may all your Christmases be amber or green,
# (for reduced eyestrain and improved visibility)!
#
#
# Notes on the Python version:
# I used a couple of `try...except curses.error' to get around some functions
# returning ERR. The errors come from using wrapping functions to fill
# windows to the last character cell. The C version doesn't have this problem,
# it simply ignores any return values.
