Hi, Walter. Since I started this, I'll give it a shot. When you download
somehting from somewhere, the two modems wait to make contact with each
other. If you are downloading, the modem sending the file sends a block of
text to your modem. If error correction is enabled, your modem will send
back to the sending modem that this block was received. Once the sending
receives confirmation from your modem that the first block was sent, the
whole process starts again and the sending modem sends another block of
information. This continues until the file is sent to you. Normally, as
you noted, this provides the best kind of download, as each block is
verified and sent again if the first attempt did not work.
However, if there are noisy phone lines, the two modems cannot
communicate with each other. When the sending modem tries to send the first
block, it waits and waits for conformation before trying to send again. Or,
if the line noise is on your end, your modem will keep trying to tell the
modem to send you more info, but the static or noise won't allow it to go
through. Hence, turning off error correction means normal (without send and
receive validation) occurs. This may result in extraneous characters
getting into a file, but usually the thing to do if line noise is the
problem is to turn off error correction or lower the baud rate.
Nick, please accept my apologies for this off topic message!!
