          scc, duart, uart - serial communication control

          bind -a #t /dev


          The serial line devices serve a one-level directory, giving
          access to the serial ports.  There are several devices serv-
          ing the same files; the particular one used depends on the
          machine involved.  Eia0 is a stream data file.  It can be
          read and written to use that port.  Reads will block until
          at least one character is available.  Eia0ctl is a stream
          control file associated with the port.  Eia1 and eia1ctl are
          similar, but for a second serial line.

          The ctl file can be used to push stream modules onto the
          port.  One can also write one of the following textual com-
          mands to a ctl file:

          bn   Set the baud rate to n.

          dn   Set DTR if n is non-zero; else clear it.

          kn   Send a break lasting n milliseconds.

          rn   Set RTS if n is non-zero; else clear it.

          mn   Obey modem CTS signal if n is non-zero; else clear it.

          pc   Set parity to odd if c is o, to even if c is e; else
               set no parity.

          sn   Set number of stop bits to n. Legal values are 1 or 2.

          ln   Set number of bits per byte to n. Legal values are 5,
               6, 7, or 8.
