Further to this thread. I have just discovered that not only does 14,400 on
this line work fine but so does 24,000. 28,800 is still stuffed tho :-(

Actually, I didn't know there was such a speed till I discovered that the
SimpleModem will force 24,000 with ATF17.

It seems very strange that the problem should be so bad at 28,800 yet not
exist at all at 24,000?

Hmmm, I'll keep testing.
