|#185837 - Data collision|
Responding to: Mahmood Elnasser's previous message
I think more than 1 phone line is available, but is it worth having 1 phone line for data and one for voice?
If data is running in both directions you need some "handshaking", e.g. a master and a slave, to prevent data collision.
With two phone lines, on the other hand, you could send all the time.
