Marty, I never solved my problem, and I tried changing many thing, but did
not change the resource nor modem, since they are so far away.
However, we loaded the software and configed PPP on another system at the
same location (the test system was the one giving up trouble), and
everything is working flawlessly.  So we have decided that if the production
system works fine, and the test give intermittent errors, we are not going
to worry about it.

Marty, the more I think about it, the more I think you are correct.  I will
concentrate on looking at the physical stuff (modem), comm resource and
perhaps the PPP config, before I start blaming the FTP client.  Come to
think of it, I used the FTP client on this box to connect to my system to
download several patches for our software, and never once had a problem
(over Ethernet as opposed to PPP).  I will be over at the client's location
tomorrow. cjg

Carl,

I bet you're just having good ol' fashioned modem problems maintaining the
connection. Can you tell, after the PPP lockup, whether the modems have
actually lost their connection (perhaps status of line description)?

I am not familiar with the 7258 but I was never a big fan of the 7852-400
compared to IBM's older "serious" modems.

Kind of tough since you don't have physical access. Given that restriction,
I would try to find the commands to add to the modem initialization string,
perhaps even a change in the LIND, that would DECREASE the speed of the
connection between the two modems (DCE-to-DCE rate) perhaps to 14400 or even
9600. Also, I would try telling the modem NOT to dynamically try to
negotiate a higher rate during the connection. Basically just make things
real easy on the modems and see if that improves the consistency of your PPP
link. Sure this is going to hurt your performace but if the reliability
improves markedly then you'll know where the problem lies.

My two cents.

-Marty

Marty, all good suggestions.  
The comm adapters are different between my machine and the customers, also
the modems, I am using a UDS V.3xxx and the customer is using an IBM
7258-400. The standard IBM FTP client does hang as well.  Sometimes it works
perfectly, other times it does not.  The modem is external, but I am in
Atlanta, with the systems group, the AS400 and other hardware is in Omaha,
so looking at the modem is out.  They have a production box I am going to
load up as well and see if the problem follows the box, the OS or the
hardware.  That will give me an idea where to hunt next.  It appears the
entire PPP link locks up, rather than just my FTP session. cjg
