# 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.
