Answer as set by +FCLASS.
DCE answers and auto-determines type.
Determine if Copy Quality OK on the T.30 flow chart. <value>=0
to 255; a value of 0 implies that error checking is disabled.
Select direct bit order.
Select reversed bit order in receiving mode for phase C data.
Allow DTE to determine the characteristics of the DCE's buffer
size.
Refer to +FCLASS Class 1 command in previous section.
No copy quality check capability.
Only check 1D phase C data.
Check both 1D and 2D phase C data.
DCE does not receive message data or poll a remote device.
