tip just says "connected" -- or dials & busy signal at same time

tip just says "connected" -- or dials & busy signal at same time

Post by Fred Lak » Thu, 14 Dec 1995 04:00:00

Help. I am using tip on a Sparc 1+ running SunOS 4.1.4 with
SupraFax 28.8 modem. The setup has worked for months and
all of a sudden starting malfunctioning ....

When I give the number explicitly, tip never dials and sez "connected"

     > #  tip 5551234

Makes no difference what number I try.

And when I start tip with a label that is an entry in
/etc/remote, then the modem dials & makes busy signal
noises at the same time.

     > # tip best
     [dials and busy noise at same time]

I am mystified. Everything worked fine for 4 months and now
it's kaput ... but for tip only. kermit and uucp seem to still
be able to use the modem just fine.

My guess is that tip is keeping state some where I can't
find -- I have rebooted the machine and reinitialized
the modem to no avail.

I would replace the modem except that it works fine
with kermit and uucp.

I feel like I am overlooking one crucial fact. All
hints welcome!



Augmented tip that came with CSLIP. Has advanced
scripting capabilities. However, I kept /bin/tip-orig
and it displays the same problem (the advanced
scripting features are not at issue since it never
gets that far.


Explicit number -- no dialing, sez connected.

Label in /etc/remote --
dials the first two or three numbers, then a busy signal
noise starts on top of the dialing; it dials a couple
more numbers, and then remainder of dialing aborts.  No
connection is made.

This happens only when I call tip with a label that is
an entry in /etc/remote.  

When the problem first started, it made ringing noises at
the same time, but now they are busy noises.

Back when it made ringing noises, then tip <number>
still worked.


kermit works fine -- at 28.8
uucp works -- at 9600 [OK, max speed of my link]
tip <number> no dial, sez connected
tip <remote-label> busy and dial at same time
  this is the crucial one, cause I use it to start TIA
  for my internet connection.

I'm sure that nothing has changed on the level I
change things. Ie /etc/remote and /etc/login.script.unix-best
are the same as they have been for months.

Was messing with X redirect in TIA true, but
that was at the remote end, how could that effect


rebooting machine -- didn't work

looking for uucp lock files which man page sez they share --
  couldn't find any in /var/spool/locks/LCK


1. modem is screwing up -- I never heard of one dialing
and ringing at same time.

2. some file or lock is in wrong state -- the last
time I sucessfully used tip, I may have exited
ungracefully, don't remember.

FILES: state of relevant files from the tip man page:

  ~/.tiprc                 initialization file
     dont have one

  /var/spool/locks/LCK ..* lock file to avoid  conflicts  with UUCP
     not there between calls [good]

  /var/adm/aculog          file in which  outgoing  calls  are logged
     cant find one    


     unchanged since things used to work

    also unchanged since things used to work, but doesn't matter
    cause never gets this far.

1. tip reports "all ports busy" on a not-at-all busy modem


    I'm running Solaris 2.3 on a SPARCstation 5.   Yesterday tip started
reporting "all ports busy" when I tried to access my modem.   I can't figure
out what to do about this.   My modem is on the "a" serial line (/dev/ttya,

can access the "b" serial line with no trouble.   All the permissions
and ownerships of the myriad filenames for the "a" device are the same as for
the "b" device.   I know that tip makes a lock entry in /var/spool/locks,
but there is nothing at all in that directory when I have this problem.
I've rebooted many times, to no avail.   I've also rebooted with the -r
switch, and forced the system to rebuild the device entries in the file
system.   That doesn't work either.    If anyone has seen this problem or
has an idea about how to cure it, I'd sure appreciate hearing about it.

                                                        Thanks for any ideas
