- Well, SLIP and DNET don't send a continuous stream of data in both directions
- the way that a protocol like BiModem would. They don't push the bandwidth
- limits NEARLY as hard. Besides, unless you're doing an FTP 'put' with SLIP,
- you're hardly going to be transmitting that much data from your Amiga.
-
- In short: SLIP and DNET (the latter of which is really just a hack, sort of a
- poor man's X windows) are not good examples of bidirectional protocols in the
- sense that I mean them (that is, sending two streams of data *continuously* as
- fast as the modem will allow).
