MsSna_ConnectionSdlc Class

A type of SNA connection that uses SDLC protocol over dial-up or leased lines.

The following syntax is simplified from MOF code.

Parameters

DialData
Data Type: String Qualifiers: MAXLEN(40) The dial data for connections which use a switched line and the phone number is not stored in the modem.

SdlcEncoding
Data Type: sint16 Access Type: Read/Write

The encoding scheme (NRZ or NRZI) for the modem to use. The following table describes the possible values for 3dlcEncoding.

Value	Description
0	NRZ
1	NRZI

SdlcEncoding must match the remote modem.

SdlcDuplex
Data Type: sint16 Access Type: Read/Write

The duplex setting of the modem. The following table describes the possible values for SdlcDuplex.

Value	Description
0	Half
1	Full

SdlcPollAddress
Data Type: String Qualifiers: MAXLEN(2) Access Type: Read/Write

A 2-digit hexadecimal number describing the poll address. Contact the administrator of the remote system to determine the appropriate value.

SdlcLeasedLine
Data Type: Boolean Access Type: Read-Only

The value depends on the Link service.

SdlcDataRate
Data Type: sint16 Access Type: Read/Write

The data rate for transmissions between the communications adapter and the modem. The following table describes the possible values for SdlcDataRate.

Value	Description
0	Low
1	High

SdlcContactLimit
Data Type: String Qualifiers: MINVALUE(1), MAXVALUE(20) Access Type: Read/Write

The maximum number of times the link service resends an XID or SNRM before declaring an outage to Host Integration Server.

SdlcContactTO
Data Type: String Qualifiers: MINVALUE(5), MAXVALUE(300) Access Type: Read/Write

The length of time, in tenths of a second, which the SDLC link service waits for an XID or SNRM response before resending the XID or SNRM.

SdlcIdleLimit
Data Type: sint16 Qualifiers: MINVALUE(1), MAXVALUE(255) Access Type: Read/Write

The number of times for the local system to try to send data to the remote system if there is no response.

SdlcIdleTO
Data Type: sint16 Access Type: MINVALUE(1), MAXVALUE(300)

The length of time, in tenths of a second, for the local system to wait for a response to a transmission before trying again.

SdlcMultiPrimary
Data Type: Boolean Access Type: Read/Write

true to indicate this is a leased SDLC line to downstream systems, and this server will be the primary station for a multidrop connection; otherwise, false.

SdlcPollLimit
Data Type: sint16 Qualifiers: MINVALUE(1), MAXVALUE(255) Access Type: Read/Write

The number of times for the local system to poll the remote system, if there is no response.

SdlcPollTO
Data Type: sint16 Qualifiers: MINVALUE(1), MAXVALUE(300) Access Type: Read/Write

The length of time, in tenths of a second, for the local system to wait for a response to a poll before trying again.

SdlcPollRate
Data Type: sint16 Qualifiers: MINVALUE(1), MAXVALUE(50) Access Type: Read/Write

The poll rate, in polls per second. Valid only if the remote system is a peer or downstream system.

SdlcStandby
Data Type: Boolean Access Type: Read/Write

true to set the Standby line to of a modem; otherwise, false.

SdlcSwitchTO
Data Type: sint16 Qualifiers: MINVALUE(10), MAXVALUE(500) Access Type: Read/Write

The number of seconds that are allowed for the user or modem to dial and make a connection to the remote computer.

MaxBtu
Data Type: sint32 Qualifiers: MINVALUE(265), MAXVALUE(16393) Access Type: Read/Write

The Maximum Basic Transmission Unit (BTU) length.

Requirements

Platforms: Windows Server 2022, Windows Server 2019, Windows Server 2016, Windows 11, and Windows 10
