Hi guys After 2 days I understand some issues with ESL and the NodeJS ESL wrapper (modesl). Learning to use event socket I read that has commands like: api - bgapi - linger, nolinger etc. Then, when reading the ESL wrapper for NodeJS I can't found those sockets commands. Only found api and bgapi, but not linger, nolinger, etc. So, the wrapper has the same methods as ESL has. But why I can't found those linger and nolinger methods? Here is the answer from the ESL wiki: *api($command, $args) is identical to sendRecv("api $command $args")* and *bgapi($command, $args) is identical to sendRecv("bgapi $command $args")* So... I can figured that "linger" or other commands should send into the "send" or "sendRecv" methods. This cause me a confussion. So, all ESL commands must be send through "send" or "sendRecv" methods, and "api" or "bgapi" are shorthands of "send" method for api/bgapi. I think these methods (api-bgapi) should be remove from ESL, to avoid future confussion. Regards Normando *//*
