No effect ... still does not display DCE speed.  Only W2 will do that
but then everything else gets messed up :-)

I like to use ATZ and keep my init string simple.  I changed M1 to M0 to
get rid of the tinny speaker noise that doesn't even handle BUSY or RING
signals.  I made that change and then wrote to NVRAM with &W.  So, as
you can see, I am using strictly factory defaults except for the speaker
being turned off with M0.

Correct me if I am wrong, but I thought that the FIFO buffer only
affected the quality of data exchange once a connection has been
established.  As I have 99.99% perfect data transfers with no overruns
or data retries, I have always used 14 in order to get the best
throughput available.  I regularly connect at 31,200 and my download
speed is always around 3260 cps with no errors ... so I don't see why I
would want to reduce the FIFO buffer size unless I misunderstand how it
works.  My major problem is trying to get DCE speed to display and I
have given up trying to get the speaker to perform adequately.
Many thanks for all your suggestions.
Bye for now ... Bob
