RE: P-t-P question

John, I have do quite a bit of PTP from the 400 and not had any problems
either.  Did you do the config with ops navigator or green screen command
ADDTCPPTP?
Also what modem are you using.   I know you can totally control the reset of
the IBM options modem and even switch between async and sync profiles.

The ZMODEM sessions attempt to send the AT Z command when they initiate.
However, the modem is not left in a command state when the P-t-P session is
ended.  Actually, a P-t-P session never gets actually started, as an FTP
will not connect.  At any rate, modem is left unusable until power switch is
cycled.

I used to do something similar in another life, so this is ancient 
recollection from the primordial soup, but all modems have a reset 
command. You need to use that to set the modem to default values.
Exactly how you do that is left as an exercise, however I dimly recall 
using an async line to pass commands to the modem. It's not necessary 
to actually dial anything via the async line. I know, this is pretty 
vague, but it's cheap too, so maybe it averages out...

I am still attempting to utilize a P-t-P connection from our 
AS/400/iSeries (whatever the name is) to another company.  Still does 
not work.  Dials the other system, but does not get a proper connection.

What it DOES do is confuse the modem.  I have several scheduled jobs 
that dial out on this modem to other organizations to trasmnit data.  
When these sessions are run, ZMODEM is used.  After my P-t-P tests, I 
use ENDTCPPTP command, and the line/controller/device are varied off.  
But, somehow, the modem is left hanging, requiring it to be turned 
off and back on.  Obviously, P-t-P over async modem is not a good 
thing if it leaves the modem useless for other data transfer jobs.  I 
am wondering if anybody has any suggestions as to how to get this 
configuration to leave the modem is a proper state for the next use?

Also, I copied the modem script from QUSRSYS/QATOCPPSCR (member
Dial400) to our
modifications library.  I edited it according to instructions in 
SF62386.  The thing I found out was that I had initially placed the 
member into the incorrect source physical file.  I copied it to the 
proper location with no problem.  But, when I tried to remove it from 
the wrong location, the remove failed.  There was a lock held on the 
member, even after ENDTCPPTP and devices were varied off.
The lock persisted until the next IPL.  Has anybody run into this, 
and, if so, were you able to get the lock removed without an IPL?

We are on v5r4.  I have no idea what cum level, as that is handled by 
the system administrator.  Potentially, this is an issue that has 
been addressed by a cum.
If I knew that, I could relay to the system administrator.


Thanks for all assistance.
