Amen. CompuServe could very easily have installed fully capable Kermit
protocol, but it chose not to do so. Readers may draw their own conclusions
as to the reason, bearing their connect-time charges in mind.
I would encourage paying CompuServe users to complain to CompuServe about
the lack of a decent Kermit (and for that matter, Zmodem) file transfer
capability, and to contact us at Columbia (and the management at Omen) if
they want to put things right. They are, after all, not exactly
cash-starved.
