telnet/descriptor.cr

Constant Summary

CONNECT_TIMEOUT = 5

Constructors

• .new(io : TCPSocket, type : Type)

Class Method Summary

• .new_client

Macro Summary

• method_missing(call)

  Forward missing methods to the TCPSocket object

Instance Method Summary

• #close
• #connect(address : String, port : Int32 = 23) : Bool

  Connect to a remote server Descriptor ends up calling TCPSocket#connect to establish the connection and we are wrapping the call so we can set @connected to true if the connection is successful.

• #connected? : Bool

  If the descriptor is a Telnet::Client instance this allows us to know if we're connected to a server yet.

• #finalize
• #type : Type

  The type of descriptor

• #write(data : UInt8)

  Write a byte to the socket

• #write(data : Array(UInt8), escape : Bool = true)

  Write an array of bytes to the socket

• #write_command(data : Array(UInt8))
• #write_command(data : Slice(UInt8))
