As for data transfer speed: I use Kermit to X-fer stuff from our Unix machine at work to my CP/M (gasp) machine at home: Kermit takes (about) 10% extra bandwidth to transmit a file (assuming text - if it's a binary it gets worse). So 4096 characters of data will need about 4500 characters transmitted over the line. Now 300 Baud is 30 CPS, hence 4500 chars take 150 seconds - 2.5 minutes, and at 1200 it's under a minute (about 40 sec). A fair estimate that will put you in the correct ballpark for data transmission is that a K takes about 10 seconds @ 1200 baud. -- dg@lakart.UUCP - David Goodenough +---+ | +-+-+ ....... !harvard!cca!lakart!dg +-+-+ | +---+
