                     14: .PP
                     15: The serial line devices serve a one-level directory,
                     16: giving access to the serial ports.
                     17: There are several devices serving the same files;
                     18: the particular one used depends on the machine involved.
                     19: .B Eia0
                     20: is a stream data file.
                     21: It can be read and written to use that port.
                     22: Reads will block until at least one character is available.
                     23: .B Eia0ctl
                     24: is a stream control file associated with the port.
                     25: .B Eia1
                     26: and
                     27: .B eia1ctl
                     28: are similar, but for a second serial line.

                     32: file can be used to push stream modules onto the port.
                     33: One can also write one of the following textual commands to a
