-> Nope. It increases the throughput by using fewer bits (8 rather than
-> 10) to represent a character. The bits are sent at exactly the same
-> speed with or without EC.
If people want more speed, Why don't they just reduce the bits to 7 or
6?
-> MF> What would be the max speed for a 28800 connection rate?
-> 28800/8 less overhead. About 3400 cps or so.
3400, I've seen close to that at a friend's house.
-> mf> Well, I can tell you, for sure, that YModem-g gives me a

-> Sure. But it _can't_ improve the number of bits the modem can handle
-> in a second, can it? It improves throughput by eliminating the
-> ZModem overhead - at the expense of Zmodem's error detection and
-> recovery. If you get a CRC error with YModem the transfer is
-> terminated.
Oh well, I could just use ZMODEM RESUME after the transfer stops.
