Signal sending level

Set the level adjustment for sending signals from 
the modem. Setting can be made over the range 
of 0 to 26 in 1dBm increments by binary inputting.
Since the maximum level differs according to 
country, if a value above the maximum level is 
set, the maximum value for the present country 
code will be adopted. (For North America and 
China, there is no limitation on the max. send 
level.)
When set to a value greater than the upper limit, it 
is considered as setting to the upper limit. When 
set to a value smaller than the lower limit, it is 
considered as setting to the lower limit.
If, however, it is set to 27 to 255, it is considered 
as setting to 26.
