(When you are typing, each character has to be embedded in a packet and transmitted; then the same has to happen with the echoed character. There may even be a built-in delay at the trans- mitter that waits a while - from may experience, maybe .2 seconds, given overall turn-around of anywhere from .25 to .5 seconds - in an attempt to build a packet with more than just on character in it. On typeout, large packets are sent; there is a delay to get typing started, but once large packets begin streaming down the link to you, the system is fast enough - >=1200 baud average - to give you continuous output.) Such systems are a pain to use for editing - believe, I KNOW; ugh! - but are VERY cheap compared to phone links. -- Jerry decvax!yale-comix!leichter leichter@yale
