1 – Identifier
o name
Simple name assigned to the link when it is created.
2 – Characteristics
o bisync code
Default: EBCDIC Value: ASCII or EBCDIC
Character code to be used on the link. This characteristic is
supported only when the characteristic protocol is set to one of
the following: bisync, chips, genbyte, or swift. You can modify
this characteristic only when the entity is disabled.
o bits per character
Default: 8 Value: 5-8
Number of bits in each character. This characteristic is
supported only when the characteristic protocol is set to
genbyte. You can modify this characteristic only when the entity
is disabled.
o buffer size
Default: 512 Value: 0-65535
Size, in octets, of each receive buffer for the link. You can
modify this characteristic only when the entity is disabled.
Also, you can only increase the characteristic value.
o control mode
Default: point to Value: See description
point
Control mode in which the link is to operate. The value of this
characteristic derives from the point to point argument to the
create command.
multipoint master
multipoint
tributary
point to point
You cannot modify this characteristic.
o crc type
Default: See Value: See description
description
CRC type used on the link.
AUTO_DIN
CRC_16
CRC_CCITT
CRC_CCITT0
LRC_EVEN
LRC_ODD
LRC_VRC_
EVEN
LRC_VRC_
ODD
NONE
The default value depends on the protocol.
BISYNC CRC_16
CHIPS LRC_EVEN
DDCMP CRC_16
GENBYTE NONE
HDLC CRC_CCITT
SDLC CRC_CCITT
SWIFT CRC_16
genbyte crc checking is done in the genbyte framing routine.
o framing timer
Default: 25 Value: 10-1000
Maximum length of time, in milliseconds, to wait for the next
character to arrive. This characteristic is supported only when
the characteristic protocol is set to genbyte.
o initial state one
Default: 0 Value: See description
First 32 bits of state information. This characteristic is
supported only when the characteristic protocol is set to
genbyte. You can modify this characteristic only when the entity
is disabled.
o initial state two
Default: 0 Value: See description
Last 32 bits of state information. This characteristic is
supported only when the characteristic protocol is set to
genbyte. You can modify this characteristic only when the entity
is disabled.
o local station address
Default: 255 Value: 0-255
Address of the local station. The default value means that only
broadcast messages are accepted. The interpretation of this
characteristic is controlled by the value of the characteristic
match station address.
This attribute is supported only if the characteristic protocol
is set to sdlc. You can modify this characteristic only when the
entity is disabled.
o match station address
Default: False Value: True or False
Specifies whether the value of the characteristic local station
address is to be interpreted as a valid address. This attribute
is supported only if the characteristic protocol is set to
sdlc. You can modify this characteristic only when the entity
is disabled.
o number of buffers
Default: 4 Value: 0-255
Number of receive buffers reserved for the link. You can modify
this characteristic only when the entity is disabled. Also, you
can only increase the characteristic value.
o physical line
Default: None Value: Local entity name
Name of the Physical layer line entity on which the link
operates. You must provide a value for this characteristic before
you enable the link. You can modify this characteristic only when
the entity is disabled.
o protocol
Framing protocol used on the line. The value of this
characteristic derives from the protocol argument to the create
command. You cannot modify this characteristic.
bisync hdlc
chips sdlc
ddcmp swift
genbyte
o sync character
Default: See Value: 0-FF
description
Hexadecimal code of the sync character to be used on the link.
The default value depends on the value of the characteristic
protocol, as follows:
bisync 32
chips 32
ddcmp 96
genbyte 32
swift 32
This attribute is supported only if the characteristic protocol
is set to bisync, chips, ddcmp, genbyte, or swift. You can modify
this characteristic only when the entity is disabled.
o sync count
Default: 4 Value: 0-255
Number of sync characters that precede each message. This
attribute is supported only if the characteristic protocol is
set to bisync, chips, ddcmp, genbyte, or swift. You can modify
this characteristic only when the entity is disabled.
3 – Counters
o abort characters received
Number of times that the link was prematurely terminated by
the remote station. This counter is supported only if the
characteristic protocol is set to either hdlc or sdlc.
o creation time
Time at which this entity was created.
o data block check errors
Number of messages received with an error in the data field block
check.
o header block check errors
Number of messages received with an error in the header block
check. This counter is supported only if the characteristic
protocol is set to ddcmp.
o invalid characters received
Number of times that an invalid character was received from
the remote station. This counter is supported only if the
characteristic protocol is set to either bisync or ddcmp.
o receive buffer overflows with good crc
Number of times that the local station received a message too
large for the receive buffer and the message had a valid CRC.
o receive overruns
Number of times that the host memory was not able to handle all
the data received from the communications channel.
o sdus received
Number of data messages received from the remote station.
o sdus sent
Number of data messages sent to the remote station.
o service octets received
Number of data octets received from the remote station.
o service octets sent
Number of data octets sent to the remote station.
o transmit underruns
Number of times that the host memory could not supply data fast
enough to satisfy the communications channel.
4 – Status
o physical port name
Name of the Physical layer port returned when the port is opened.
If this value is missing, the port has yet to be opened.
o state
State of the frame link entity.
off The link is disabled.
on The link is enabled.
o uid
Entity's unique identifier, which is generated when the entity is
created.
