NAME

       flarq - ARQ data transfer utility for fldigi

SYNOPSIS

       flarq [OPTIONS]

DESCRIPTION

       Flarq (fast light automatic repeat request) is a file transfer application that is based
       on the ARQ specification developed by Paul Schmidt, K9PS. It is capable of transmitting
       and receiving frames of ARQ data via fldigi, as well as MultiPSK on Windows.

OPTIONS

       Long options begin with two hyphens and are handled by flarq. The option names may be
       abbreviated to any unambiguous substring, and the option argument may be separated from
       the name by a space or equals sign, as per getopt(3).

       Short options begin with a single hyphen and are passed directly to FLTK. They may be
       abbreviated only as indicated.

       --arq-protocol TYPE
           Set the ARQ protocol. May be either “fldigi” or “multipsk”. Defaults to “fldigi”.

       --arq-server-address HOSTNAME
           Set the ARQ TCP server address. Defaults to “127.0.0.1”.  HOSTNAME may be any node
           name string accepted by getaddrinfo(3).

       --arq-server-port PORT
           Set the ARQ TCP server port. Defaults to “7322”.  PORT may be any service name string
           accepted by getaddrinfo(3).
