S REGISTERS
Introduction
Your modem contains a number of registers — memory stores — which
define the modem’s operating characteristics. These registers are called
Special Registers or S Registers.
This section of the PRO16 Reference Guide shows you the function and
usage of each S Register, how to check the current contents of your S
Registers, how to change S Register settings and how to save the settings
in non-volatile memory.
Reading and Changing S Registers
The Read Register command (Sn?) enables you to check the current
contents of an S Register.
For example:
To check how long the modem will wait for a dial tone before starting
to dial, you would check S Register 6. To do this:
• Type: ATS6? <E>
The modem will display the current contents of the S6 Register.
If you want to change the register setting, use the Set Register command
(Sn=x).
For example:
To change the setting of your modem, so the modem waits five seconds
for a dial tone before starting to dial:
• Type: ATS6=5 <E>
S Register Settings and Modem Memory
Your modem comes configured with a set of default values for each of
the special registers. Any changes you make using the Sn=x command
will only last while the modem is switched on.
Once you switch the modem off, these changes will be lost and the next
time the modem is switched on, the factory-set default values will be in
effect.
