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 either vbdigi on Window, or fldigi on Linux.  The interaction between flarq and vbdigi/fldigi requires no operator intervention.  On the Windows OS the two programs exchange data and command sets using files that both programs recognize. On the Linux OS the exchange is made using the System-V Message Queue.  This process is totally transparent to the user.  The programs can be executed in either order.  It is only necessary that both be executing concurrently for the process to work.

The ARQ transfer must take place between two systems both of which are running the flarq/vbdigi (or the flarq/fldigi in Linux) combination.  The ARQ specification and the source code for flarq are LGPL licensed.  Other developers wishing to duplicate or expand upon the flarq ARQ implementation may freely do
