per 506 bytes of message instead of 16 bits of CRC. More robust
EC's exist if someone has good data on what errors need
correction. This FEC alone will make a very big difference to a
marginal voice or asynch digital channel. It can be cheaper than
the cost difference between an error correcting modem and a
normal modem to let the CPU spin a dozen extra instructions per

I have implemented LAPB on asynch and I think that FEC+IP+TCP
would be faster, more reliable, and less software.
