TCP/IP network of any configuration, UDP protocol. If you need something special, please contact our .
Do not forget to allow local/remote ports in firewalls.

Connecting, Login and Registration.

- New user. Call Connect then prepare UserInfo (you must set UserName at least) and register new user.
Connection settings can be tuned in ConnectionParams before connecting.
You can add connecting depended specific actions by setting BeforeConnect and/or AfterConnect event handlers.

Connect or RegisterNewUser implicitly calls Logon. You should specify Password property before calling one of these methods. You must be logged to get the full access to the server. If the user is connected but not logged, it is in a guest mode (Connected is set to True, Logged is set to False, UserID is equal to MSG_INVALID_USER_ID default value). In the guest mode, the following commands are available only to enable you to switch to a full access mode and to get some information from the server you possibly need to logon or to register a new user: Logon, RegisterNewUser, IsUserExisting, FindUsers.
