+                           TENEX FTP PROBLEM
+
+   Tenex users of FTP should beware of a problem in the current Tenex
+   implementation which is likely to cause incorrect results when
+   transferring files to a non-Tenex site.  Some Tenex programs create
+   an ASCII US (Unit Separator) character as an end-of-line indicator,
+   instead of CR LF.  The current Tenex FTP user implementation passes
+   these US characters over the Network instead of translating them to
+   CR LF as required by FTP protocol.  If the recipient is not a Tenex,
+   he will not do anything special with these US characters and the line
+   spacing will be lost. In the case of sending to CCN, we will treat it
+   as a very long logical record and fold it into successive 360
+   records.
+
+   A circumvention is to pass the Tenex file through some Tenex program
+   that does the necessary conversion before sending it over the
+   Network.  We know that TECO will remove US's; there are probably
+   other means.  Loading and saving the file with TECO will replace all
+   US's with CR LF sequences.
