Allows you to display the communication characteristics for a
    specific terminal.

    Format

      SHOW  device-name[:]

1  –  Parameter

 device-name[:]

    Supplies the name of the device whose characteristics are to
    be displayed. The device name has the form ddcu where dd is the
    device code, c is the controller designation, and u is the unit
    number. LAN devices are specified as the name of the device that
    is unit 0. For example, the first terminal device on a LAN is
    specified as TTA0, the second as TTB0.

2  –  Qualifiers

2.1    /ADDRESS_COMPRESSION

2.2    /ALL

       /ALL[=BRIEF] (default)
       /ALL[=LONG]

    Displays all the current device and communication settings. BRIEF
    formats the output for the screen. LONG displays each setting on
    a separate line.

2.3    /COUNTERS

       /COUNTERS=(keyword,...)

    Shows the current values for the specified counter(s). You
    can specify one or more of the following keywords with this
    qualifier:

    Keyword          Description

    ALL              Displays all counters.
    BAD_FCS_PACKETS  Displays the count of packets with bad frame
                     check sequence (FCS).
    DATA_LOST        Displays the count of lost characters that were
                     reported by hardware.
    DROPPED_         Displays the count of all characters thrown
    CHARACTERS       away.
    FRAMING_ERRORS   Displays the count of characters with framing
                     errors.
    LONG_PACKETS     Displays the count of packets longer than the
                     current maximum receive unit setting (MRU).
    RECEIVED_        Displays the count of total packets received.
    PACKETS
    RUNT_PACKETS     Displays the count of packets with too few
                     characters.
    TOTAL_           Displays the count of all characters received.
    CHARACTERS
    TRANSMITTED_     Displays the count of total packets transmitted.
    PACKETS

2.4    /ECHO

       /ECHO=(FAILURE=value, INTERVAL=value)

    Specifies the number of Link Control Protocol (LCP) echo requests
    and the interval (in milliseconds) between requests that must be
    sent without response before the line is considered down.

2.5    /FCS_SIZE

    Shows the current receive and transmit FCS size in bits.

2.6    /FLOW_CONTROL

       /FLOW_CONTROL=(keyword,...)

    Shows the current flow control setting used over the asynchronous
    physical link. You can specify one of the following keywords with
    this qualifier:

    Keyword    Description

    HARDWARE   Uses RTS/CTS flow control. If using this control, the
               transmit Asynch Control Character Map (ACCM) can be
               0x0, 0x0, 0x0, 0x60000000. Only valid for lines set to
               /MODEM or /COMMSYNCH.
    XON_XOFF   Uses band flow control. If using this control, the
    (de-       optimal transmit ACCM is 0xA0000, 0x0, 0x0, 0x60000000.
    fault)     Only valid for asynchronous lines.

2.7    /HANGUP

    Displays the action that occurs when a session is terminated.

2.8    /MAGIC_NUMBER_RETRIES

    Shows the number of attempts that are made to negotiate a magic
    number.

2.9    /MAXCONFIGURE

    Shows the number of configure-request packets sent without
    acknowledgment before assuming that the peer is not responding.

2.10    /MAXFAILURE

    Displays the number of configure-nak packets sent before sending
    a configure-ack and before assuming that the configuration is not
    converging.

2.11    /MAXTERMINATE

    Shows the number of terminate-request packets sent without
    acknowledgment before assuming the peer is unable to respond.

2.12    /MRU

    Displays the largest packet that the line can receive.

2.13    /MTU

    Displays the largest packet that the line can transmit.

2.14    /NETWORK_PROTOCOL

    Displays the current network protocol(s) allowed over the
    physical link.

2.15    /PASSIVE

    Indicates whether this is a passive or active line.

2.16    /PERMANENT

    Indicates whether this is a permanent or transient (nonpermanent)
    line.

2.17    /PROTOCOL_COMPRESSION

    Shows the status of protocol field compression.

2.18    /RECEIVE_ACCM

    Displays the value of the current receive ACCM for asynchronous
    ports.

2.19    /RESTART_TIMER

    Displays the interval used to time transmission of request
    packets.

2.20    /SPEED
