V.8 in Manual Reception

manual reception, though some other fax machines do not.

Shift-down Conditions
One-step Shift-Down from the Receiving Terminal

terminal.
If the machine has sent two PPRs for one ECM block, it will request the sending
terminal to make a one-step shift-down in the next control channel.
N eor: Number of frame re-transmissions remaining until the Tx terminal sends
DCN to terminate the communication. This is fixed at "9", and is not
adjustable.
