Considerations

The LINK_STATION_OEM_SPECIFIC_DATA parameter defines a link station. Refer to the following example from a .ACG configuration file:

LINK_STATION_OEM_SPECIFIC_DATA=(
	OEM_LINK_DATA=(
		OEM_DATA=010000000400000004000000030000000F00000001000000
		OEM_DATA=0F000000DE01A8C0
	)
)

Take the OEM_DATA fields and concatenate them in order, as follows:

010000000400000004000000030000000F000000010000000F000000DE01A8C0

Then break that into 4-byte words:

Reverse the order of the bytes, as follows:

The fields are as follows:

00000001: Link Type—only value allowed
00000004: DSAP (Remote SAP)
00000004: SSAP (Local SAP)
00000003: XID retry count (Connect retry count)
0000000F: XID retry timer (Connect timer)
00000001: Reserved
0000000A: Liveness timer (Inactivity timer)
C0A801DE: IP address (Remote IP address)

Note:

All values are in hexadecimal notation.
The names in parentheses are the parameter labels in the EEDLC Connection tab of the EEDLC link station definition in the SNA Node Configuration tool.
Other than the IP address, all the values shown are the default values. There is no default IP address.
When you change one of these values in the Node Configuration tool and save to the .ACG file, the relevant byte of OEM_DATA is changed in the configuration file.

For the IP address, convert each byte to decimal to obtain the IP address. The above example converts to 192.168.1.222, as follows:

C0: 192
A8: 168
01: 1
DE: 222

If you enter a host name instead of an IP address, the IP address field becomes the length of the host name, and the host name (in ASCII hex codes) is appended, with a trailing 00 byte to mark the end. The bytes of the host name are not swapped. See the following example:

LINK_STATION_OEM_SPECIFIC_DATA=(
	OEM_LINK_DATA=(
		OEM_DATA=010000000400000004000000030000000F00000001000000
		OEM_DATA=0A000000150000006C6F63616C686F73742E6C6F63616C64
		OEM_DATA=6F6D61696E00
	)
)

Concatenation produces the following:

010000000400000004000000030000000F000000010000000A000000
150000006C6F63616C686F73742E6C6F63616C646F6D61696E00

Breaking it up into words and swapping bytes (except the host name) produces the following:

00000001: Link Type—only value allowed
00000004: DSAP (Remote SAP)
00000004: SSAP (Local SAP)
00000003: XID retry count (Connect retry count)
0000000F: XID retry timer (Connect timer)
00000001: Reserved
0000000A: Liveness timer (Inactivity timer).
The range of valid values is 1–255 seconds.
