Status Registers
This chapter provides an overview of S-Registers (status registers) available in your U-
90E data/fax modem.

The descriptions for each S-register are given below. In most bit-mapped S-registers, the
default bit value is 0. An asterisk marks non-0 default values. In some cases, default
values are shown in the reference column preceded by +. Some bits are reserved for
factory use and should not be changed.
