 RLogin is often used to connect BBS users to "door game servers"​ because of the protocol'​s ability to transparently pass the login-ID of the user as part of the initial connection establishment. If the door game server recognizes the user's credentials,​ it can automatically authenticate the user and in some cases immediately launch a specific door game of interest. RLogin is often used to connect BBS users to "door game servers"​ because of the protocol'​s ability to transparently pass the login-ID of the user as part of the initial connection establishment.

 +===== Protocol =====
 +Only the initial RLogin connection establishment is supported; the other RLogin protocol features ("​cooked mode", out-of-band sequences, e.g. Window size) are not supported.
 +
 +==== Binary Data ====
 +Unlike Telnet, there is no "​binary mode" option that can be negotiated, so some characters (e.g keystrokes) sent from the remote user will always be interpreted on the host BBS and not sent to the remote server. This means that binary data transfers (e.g. file transfers) through an RLogin gateway may not always work as expected.
  
 ===== Telgate ===== ===== Telgate =====
  
-The RLogin module is just a thin script that calls the Synchronet JavaScript ''​bbs.rlogin_gate''​ method which in turn is just a thin wrapper function around the Synchronet C++ ''​telnet_gate''​ function. Although this function was originally created for creating proxy gateways using the Telnet protocol, it was later enhanced to also support the RLogin protocol, but was not renamed. So the internal Telnet Gateway (telgate) functionality is utilized to create RLogin gateway connections as well.+The RLogin module is just a thin script that calls the Synchronet JavaScript ''​bbs.rlogin_gate()''​ method which in turn is just a thin wrapper function around the Synchronet C++ ''​telnet_gate()''​ function.

 ===== Usage =====  ===== Usage ===== 
-The RLogin module is normally executed via a command-line configured [[util:​SCFG]],​ often as an "​External Program"​. By convention, JavaScript modules are executed by prefixing ​the module name with a question mark (''?''​) symbol. An asterisk (''​*''​) prefix will also work, but will fall back to execute the old ''​[[dir:​exec]]/​rlogin.bin''​ if the ''​rlogin.js''​ is missing.+The RLogin module is normally executed via a command-line configured ​in [[util:​SCFG]],​ often as an "​External Program"​.
