The content of the B900ss-20 operating parameters are found in named
'S' registers, and are numbered as described in Chapter VII- 3. Some
parameters are standard for all the Hayes Modems; others are specific to
B900ss-20.
(See Table in Appendix 6).
If the requested register is correct, the modem responds: ''Sxxx=yyy" with
xxx: register number and yyy: register content.
If the requested register is incorrect, the modem responds with the error
character 'E' (0x45).
These parameters are saved in EEPROM Memory and automatically
reloaded during a reset or when powered up.
