- Showing total disregard for conventional net.wisdom, on this date a
- lowly 386SX-16 clone has successfully completed a 500KB data transfer
- at 9600 bps using a Digicom Scout Plus internal modem and the Windows
- Terminal program. The transfer completed with ZERO retries using the
- XMODEM-CRC protocol with 1K blocksize. Measured average throughput
- was 744 cps, or 77% of the theoretical limit of the async channel.
- (The channel imposes a 2-bit overhead on each byte, so the useful
- bandwidth is 7680 bps or 960 cps.)
-
- Please pardon my astonishment.
