Default login to 40 chars with no graphics
With more people using retro computers, either physical or emulated, I'm finding a number of them only have 40 columns or default that way (BBC Micro, ZX Spectrum, TRS80, to name a few) and none of them have ansi graphics.
Maybe add an option for the sysop to turn on a plain text, 40 column mode if it cannot reliably determine the terminal is 80 columns and can go ansi graphics through detection.
This leads me to a second suggestion that I will file separately.
