RS-232-like MIB (RFC 1317)
The "rs232" object defined by RFC 1317 is supported for the MODEM port and the
COM port. The RS-232-like MIB consists of one object and five tables, as follows:

The Input Signal and Output Signal Tables are not supported for the MODEM and
COM ports. The following sections provide clarification for objects contained in the
RS-232-like MIB when it is not clear how the object definition in MIB is related to
the CSU.
Number of Ports – "rs232Number" Object (rs232 1)
This object contains the number of ports in the RS-232-like general port table. This
number is 3 for the 3150 CSU and 1 for the 3151 CSU when the COM port is
enabled.
General Port Table, RS-232-like MIB
The general port table contains general configuration objects for the RS-232-like
interfaces.
General Port Table – "rs232PortIndex" Object (rs232PortEntry 1)
This object contains a unique value for each port and is used as an index into the
general port table (rs232PortTable). The values of the rs232PortIndex object vary
between models and are listed below.
The values of rs232PortIndex for the 3150 CSU are:

The value of rs232PortIndex for the carrier 3151 CSU is:
