DTR problems with AUX 1.0

[Alex Nghiem]

Has anyone had problems setting up modems for dialup with AUX? We
are using a Microcomm 9600+, a Microcomm 2400+, and an Everex 2400
externals. In all cases, the modems will not answer the phone under
AUX.

It appears that gettydef and initdef and all modem switches are
set up properly. The DTR light indicates that DTR is high as it
should be. 

When we turn around and boot MacKermit under Mac OS, the modems
answer correctly. When we connect our modems to our IBM Xenix
machine, the modems answer correctly.

Is there a problem with the way AUX raises DTR? Why is it that
the modems answer correctly under Mac OS, but does not answer
under AUX. Does AUX raise DTR to constant EIA levels or
does AUX "pulse" DTR at some high frequency?

Thanks,
