communicator and a remote modem. The communicator can compress data and send
it faster. Their value can be changed by using the '+/-' key. The following features are
available:
ƒ
Modulation : Auto or V34 transmitting the point during connect negotiation at

before any error. Note that V34 option can solve the problem of working with
old equipment computers.
