+.Tn EIA
+.Tn RS-232C
+.Pf ( Tn CCITT
+.Tn V.28 )
+communications interfaces.
+.Pp
+The NS8250 and NS16450 have single
+character buffers, the NS16550 has a 16 character buffer, while
+the ST16650 has a 32 character buffer.  The XR16850 has a 128 character
+buffer.
+.Pp
+Input and output for each line may set to one of following baud rates;
+50, 75, 110, 134.5, 150, 300, 600, 1200, 1800, 2400, 4800, 9600,
+19200, 38400, 57600, or 115200, or any other baud rate which is a factor
+of 115200.
