So you suggest that a Milan should have modem1 (MFP), modem3 and modem4, but
no modem2? Not very useful. A Milan without MFP-driven serial port would
then have only modem3 and modem4.

No. A standard falcon has no mfp-driven serial port. There are two SCC
channels, labeled "modem" and "LAN".

Furthermore, I see really no advantage in having separate names for ports
with CD and without CD. When used consequently, this would lead to different
names for
 - full ports (9 lines)
 - full port, but without RI
 - port with only RxD, TxD, RTS and CTS
 - Falcon MFP: only RxD+TxD
 - LAN

plus other varieties that might come up. It is nice to know about these, but
an ioctl call seems much more appropriate for this purpose to me.
