Very Computer

I am having problems with my modem - not sure if it has always
been the case or not.  (I do not think it has always been the case.)
When using kermit (after reboot I get):

/dev/modem: Device or resource busy

If I (as root) do:
kill (the getty on /dev/ttyS1) ; dir > /dev/modem
all will be fine from this point on. If I dont write to /dev/modem
the modem still will be busy - getty respawns too fast and I cant use it.
Or if someone were to dial in before I attempt to use the modem
after a reboot - things will also be fine.  

I program my internal modem (Practical Peripherals 14400FX):

at&F1&Q9M0&D3S0=2E0Q2&W

which if I do at&V I get:

OK

I have pl14 and no other boards using that IRQ (5) and my recompiled kernel
has been working fine for quite awhile (at least a month).

An strace of the kermit pid shows a failure to open the device
which tells me there are no locks on the modem.

Of course - it is very possible I dont know what I am doing and the
answer is obvious.  The Serial Howto mentions this problem - it says to
check DCD - make sure its only on when a connection is made which according
to my modem docs &C1 is the settings that I should have.
It also mentions other possibilities - which have not panned out.

Any help would be greatly appreciated and paid back with a virtual beer.
(Or at least a nice jpeg of a neat beer label.)

I don't know if this is the same problem, since you're running pl14.  I had
the same symptom with pl15j.  I applied the getty_ps 2.0.7b -> 2.0.7c patch
(in sunsite.unc.edu:/pub/Linux/system/Serial).  The message in the patch said
that getty_ps 2.0.7b was broken by pl15.  So, good luck!
