Uucp normally won't be able  to  function  over  a  network  that
doesn't  provide  a  full  8-bit  transfer mode. Occasionally its
going to generate characters like ^S/^Q in its headers and if the
network is going to gobble them up its not going to work.

If you have source then you might add in  a  new  protocol.  Uucp
allows  for  more  that the default 'g'-protocol so you could add
one that avoids this problem. In the UK many sites use a modified
uucp  that  gives  you  the choice between using a variant on the
standard 'g'-protocol and the 'f'-protocol. The  former  converts
all  messages  into  text  on sending and back to binary again on
arriving so that Unix and networks can do  what  they  like  with
control chars for flow control. If you have very clean lines then
you might  care  to  use  the  'f'-protocol.  It  does  something
similar, except it presumes that you never corrupt characters and
that TANDEM mode is enough to prevent losing stuff.
