| Post-initialization value: | 0 (disabled) |

 This setting defines whether the DS will perform Link Service login procedure after a TCP data connection with another network host is established . For more information on Link Service see Link Server Documentation.
 Link Service logins use the data from the following settings of the DS: Owner Name (ON) , Device Name (DN) , and Password (PW) setting ). The password is supplied in the encrypted form so Link Service logins are secure.
 Link Server Login is irrelevant when  Current Transport Protocol (TP) [setting /parameter ] = 0 (UDP) because UDP/IP cannot be used for communications with the Link Server.
