This object indicates Status of parameters specific to the
selected port.
- For a port that has no special status or is supported
  by prtSExHsfStatTable - 1 Octet: 00hex

- For VC-6, VC-12, VC-12/6 external ports - 1 Octet :
  Bit 7 (MSB)..Bit 2 = 0 (NA)
  Bit 1:       Tx Signaling '1'=On ; '0'=Off
  Bit 0 (LSB): Rx Signaling '1'=On ; '0'=Off

- For VC-6A and VC-6AG external ports - 1 Octet :
  Bit 7 (MSB)..Bit 3 = 0 (NA)
          Bit 2:       ADPCM module '1' =Exist ; '0' =Not Exist
  Bit 1:       Tx Signaling '1'=On ; '0'=Off
  Bit 0 (LSB): Rx Signaling '1'=On ; '0'=Off

- For VC-2/R2(FXS) external ports - 1 Octet :
  Bit  -   7 6 5 4 3 2 1 0

- For ML-20 external port - 3 Octets :
  - 1 MS Octet will represent the Real Rate used:
        Bit    - 7 6 5 4 3 2 1 0
                 |___| |_______|
           spare  Rate

    Valid values: 0..31, meaning 0..31x64Kbps
    Invalid values: 32..255.
  - 2 LS Octets will represent the Status of 7 Control
    Signals:
    Signal - ---  CTS  DSR  DCD   RJ   TM   DTR  RTS
    Bit   - 7 6  5 4  3 2  1 0    7 6  5 4  3 2  1 0
    Octet  -          2                     3 (LS)
    '---' will always have the value 00
    Rest of the Signals (2 bits each) can have the following
    values:
    00=NA   ;  01=unused ; 10=Off  ; 11=On
