I'd thought of suggesting Kermit, the question is, is there a version that
is available for RSTS/E (especially if it's V7.x)?  The freeware archives
for RSTS/E are pretty slim.  Then there is that whole serial port issue.

  .  Unfortunately, it requires
RSTS/e 8.0 or later.    I do not know if one of the RT or RSX versions
would fill the bill on earlier RSTS/e versions.
