Another possible way to handle flow control would be to use the old HDLC link layer protocol that goes by the name of LAPD, V.42, called-something-else-in-GSM, etc. You'd want the version that starts with a SABME command (Set Asynchronous Balanced Mode Extended). There's probably a free implementation somewhere.
IIRC it can be implemented with two timers and a pretty small state machine. Might be more amenable to an FPGA implementation than TCP. Eric _______________________________________________ Discuss-gnuradio mailing list [email protected] http://lists.gnu.org/mailman/listinfo/discuss-gnuradio
