buffer overflows when using CCGMS-5.5 as the client terminal. File
transfer rates were unaffected when there was no on-screen display. One
could easily see the difference between Color 64 at 2400 baud and AABBS
at 2400 baud. I imagine AABBS might have run fine using a client
terminal in black and white mode. Perhaps it was something to do with
the C64 color and graphics set."
