Modem Operation
4.4.9 Sn=x (AT[0–40]=[0–255])
= Set S register
The LAN-Modem has 41 S registers (S0 to S40) which
determine its operating behavior. The command Sn=x is
used to overwrite the current contents, whereby „n“ specifies
the desired register and „x“ the value to write in decimal
format. Only the following registers presently have meaning
for the operation of the LAN-Modem:

S2
S3

Note the following when writing to the S registers of the
LAN-Modem:
• The command Sn=x has only a temporary effect. The
changes can be loaded into the non-volatile memory
of the LAN-Modem by using the
&W command. The
only exceptions are registers S3, S4 and S5 . These
cannot be permanently stored.
• Registers S14, S21, S23 and S39 should not be accessed
by direct writing, but rather via the corresponding AT
commands.
