Re: Times change
The 2400 baud sort of gives it away that that was in the days before zmodem allowed a transmission resume.
That reminds me of a friend of mine who had a fairly popular BBS. In those days, it was deemed an act of decency if you uploaded 5..10% of the volume you downloaded, but not all did. He had an interesting solution to that: with frequent abusers, he aborted the connection several bytes from the end which would force the user to start downloading all over again on reconnect. It sometimes took three to four times before they worked out that this wasn't bad luck but deliberate.
The later emergence of zmodem and its resume function spoiled this somewhat :).
