---------------
Formatted (file transfer) screens do cost a little with MSK too,
but very little unless very high speeds (or an unusually slow video system)
are used. As a guide on inherent speed as seen at my site, MSK on a 486-66
gets about 80+KB/sec for file transfers to our campus DEC Alpha cluster,
upon which CKermit is running. This is over Telnet (Ethernet topology) and
no unprefixing done and the display left drawing its bar across the screen.
Sort of out of the box MSK but with 1KB packets and 4 window slots. CKermit
was running in server mode on the Alphas, and it had no separate screen.
