At a leased line configuration the modems have to operate with different
channel allocations. It is not possible to establish a connection without
setting the command AT&L(n) as a first operation. This adjustment is
necessary for synchronous as well as for asynchronous applications. The
example presented here is realized using a terminal or personal computer
with a special data transmission software.
