Summary: 

AT&T sells a product of LOCUS called PC Interface.  (Colloquially, the
"smooth bridge to unix".)

PCI is a file server.  The unix file system appears as an enormous "disk"
to users and prorams running on DOS with PCI installed.  For example, if your
PC has two floppies, "A:" and "B:", the unix directory tree will appear as
disk "C:".  This allows users to store much larger amounts of data than would
fit on their PC's floppy or hard disk.  In addition, the files are visible;
other users (on other PCs) can see and access the files (subject to the file
permissions, of course).

PCI also includes a terminal emulator that allows the user to access unix as
though his PC were a VT100.  (I believe other terminal types may be emulated
in the future.)  The user can switch back and forth between DOS and his unix
terminal session(s).

PCI normally accesses the unix host through an ethernet connection, but 
it can function over an RS232 line if no ethernet is available.  (Of course,
RS232 is slower!)
