8.3 Call progress

     When FD has mail to send, it will step through the mail queue and
     call the systems with mail packets waiting. Packets with sent,
     failed, and hold status are ignored by FD. These can, however,
     always be picked up by the destination system if it calls in.

     After every unsuccessful (BUSY, NO CARRIER, etc.) call, the busy
     retry counter is incremented until it reaches the value defined
     in FDSETUP. Once the limit has been exceeded, FD puts hold status
     on the packet. If a connection is made but the actual transfer
     fails, the resend retry counter is updated and once the limit,
     defined in FDSETUP, is reached, FD puts failed status on the
     packet.
