set [node node-id] frame link link-id ...
Modifies the attributes for an frame link entity, which is
associated with a physical line and controls the framing protocol
used on that line. The modifiable attributes and their data
types [in brackets] are:
bisync code [ASCII-or-EBCDIC]
bits per character [integer]
buffer size [integer]
crc type [crc-type]
framing timer [milliseconds]
initial state one [state-info]
initial state two [state-info]
local station address [integer]
match station address [on-or-off]
number of buffers [integer]
physical line [local-entity-name]
sync character [octet]
sync count [integer]
Examples:
set frame link frame-0 bisync code EBCDIC, -
framing timer 25, number of buffers 6
set frame link frame-1 match station address on
1 – 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.
2 – 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.
3 – 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.
4 – crc_type
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.
5 – 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.
6 – initial_state_one
Default: 4
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.
7 – initial_state_two
Default: 4
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.
8 – 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.
9 – match_station_address
Default: Off Value: On or Off
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.
10 – 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.
11 – physical_line
Default: none Value: Local entity name
A local entity name specifying the physical layer line entity on
which the link entity is to operate. A non-null value must be
set before the link can be enabled. Can only be set when the
link is off.
12 – sync_character
Default: See description Value: 0-FF
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.
13 – 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.
