[net.unix-wizards] problem with 801 ACU on USG 3.0 UNIX

bis (05/28/82)

We have run into several failures with the "cu" process
being able to dial into external networks. It appears that
the dialers work for the first few times they are tried but
as the day progresses we start experiencing more and more
failures of the call mechanism. Usually if we try the 
dial process several times in succession, we will
finally get through. The returned message from the cu
process seems to have no real consistance. In some 
instances it will indicate the dialer is hung and
in others it will indicate that the line or acu device
does not exist.
