                         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.
