Anything is possible.

The software vendor wanted to create a new line.  I'd rather use the ECS 
line my self.  I think all I would need to do is change it to autoanswer.

Very true.  I mentioned it so people wouldn't ask me If the line was varied 
on and if it was in a connect pending state.  Which is obviously a 
requirement before the modem will answer the phone.

Actually there are two.  The other phone line is used to connect to the 
internet.  The software vendor insists on calling in from their AS/400 
directly to the ECS modme.

And this would certainly be better.  Some software vendors aren't open to 
suggestions.  They created this configuration and want me to fix it.

Kind of.  There is a special cable for the ECS line 44H7486 spelled out in 
Setting up your 9401 model 150 on page 1-15.  It is an Enhanced 
Communicaton Cable.  The other modem is using a standard RS232V.24 
cable Non-Enhanced 44H7480 spelled out on page 1-21.

AS/400 IBM ecs modem.  

This is a problem before the other system ever gets involved.  This modem 
won't answer any call.  In order for any modem to answer a call the TR 
light must be on.  

Thanks for helping.
