DLC_TRCO |
Trace control on:
0 = Disable link trace.
1 = Enable link trace. |
DLC_TRCL |
Trace control long:
0 = Link trace entries are short (80 bytes).
1 = Link trace entries are long (full packet). |
DLC_SLS_STAT |
Station type for SDLC:
0 = Secondary (default)
1 = Primary |
DLC_SLS_NEGO |
Negotiate station type for SDLC:
0 = No (default)
1 = Yes |
DLC_SLS_HOLD |
Hold link on inactivity:
0 = No (default). Terminate the LS.
1 = Yes, hold it active. |
DLC_SLS_LSVC |
LS virtual call:
0 = Listen for incoming call.
1 = Initiate call. |
DLC_SLS_ADDR |
Address indicator:
0 = Remote is identified by name (discovery).
1 = Remote is identified by address (resolve, SDLC). |
trace_chan
|
Specifies the channel number obtained from the trcstart subroutine. This field is valid only if the DLC_TRCO indicator is set active. |
len_raddr_name
|
Specifies the byte length of the remote address or name. This field must be set to 0 if no remote address or name is required to start the LS. Length values of 0 through 20 are supported. |
raddr_name
|
Contains the unique network address of the remote node if the DLC_SLS_ADDR indicator is set active. Contains the unique network name of the remote node if the DLC_SLS_ADDR indicator is reset. Addresses are entered in hexadecimal notation, and names are entered in character notation. This field is only valid if the previous length field is nonzero. |
maxif
|
Specifies the maximum number of I-field bytes that can be in one packet. This value is reduced by GDLC if the device handler buffer sizes are too small to hold the maximum I-field specified here. The resultant size is returned from GDLC when the link station has been started. |
rcv_wind
|
The receive window specifies the maximum number of sequentially numbered receive I-frames the local station can accept before sending an acknowledgment. |
xmit_wind |
Specifies the transmit window and the maximum number of sequentially numbered transmitted I-frames that can be outstanding at any time. |
rsap
|
Specifies the remote SAP address being called. This field is valid only if the DLC_SLS_LSVC indicator or the DLC_SLS_ADDR indicator is set active. |
rsap_low |
Specifies the lowest value in the range of remote SAP address values that the local SAP responds to when listening for a remote-initiated attachment. This value cannot be the null SAP (0x00) or the discovery SAP (0xFC), and must have the low-order bit set to 0 (B`nnnnnnn0') to indicate an individual address. |
rsap_high
|
Specifies the highest value in the range of remote SAP address values that the local SAP responds to, when listening for a remote-initiated attachment. This value cannot be the null SAP (0x00) or the discovery SAP (0xFC), and must have the low-order bit set to 0 (B`nnnnnnn0') to indicate an individual address. |
max_repoll |
Specifies the maximum number of retries for an unacknowledged command frame, or in the case of an I-frame timeout, the number of times the nonresponding remote link station is polled with a supervisory command frame. |
repoll_time |
Contains the timeout value (in increments defined by the specific GDLC) used to specify the amount of time allowed prior to retransmitting an unacknowledged command frame. |
ack_time |
Contains the timeout value (in increments defined by the specific GDLC) used to specify the amount of time to delay the transmission of an acknowledgment for a received I-frame. |
inact_time |
Contains the timeout value (in increments of 1 second) used to specify the maximum amount of time allowed before receive inactivity returns an error. |
force_time
|
Contains the timeout value (in increments of 1 second) specifying the period to wait for a normal disconnection. Once the timeout occurs, the disconnection is forced and the link station is halted. |
