    Thanks for the thought. The basic problem is that my phone is about 12 
km from the BT phone station. Even at the speed of light, the signal delay 
would be about 40 micro seconds each way, so a transmit + ACK would be >80 
micro seconds assuming that the rest of the system were infinitely fast. 
This delay severely limits the communication speeds when you are sending 
single bytes.
    That way around it is to use a system which sends a large information 
packet. However, I can just about cope at the moment.
Hey, when we get to heaven we will have all the speed and bandwideth we want 
...... I wonder if there will be any earthquakes??
