Transfering data and I'm getting a big difference measured vs calculated ...
Ascii 7bits+1start+1parity+1stop = 10 bits per character Baud = 9600 Characters per second = baud / bits per character => 960 characters per second
File size to transfer = 8.88 kilobytes = 9093 bytes = 72745 bits
(72745 bits/file ) / (10 bits/character) = 7274 characters per file
Hyperterminal transfers file @ 9600 baud via nullmodem cable to another computer in 12 seconds. My calculated transfer of file is 7274 characters / 960 characters / second = 7.58 seconds.
At 2400 baud , 240 characters per second I get a transfer time of 41 seconds calculated = 7274 characters / 240 characters per second => 30.3
Why should I be getting such large differences?
