Problem with mac os launched applications in AUX

[Aeagb-s07 at heidelberg-emh2.army.mil]

We have Mac II's runnis AUX version 1.1 and are encountering problems with
Mac OS and/or AUX launched applications sending information to the printer.
When the machine is in the MAC OS modes there is no problem with printing,
however when the application is launched within AUX there is not print 
capability out of the serial port.

Any Assistance or existing source code available would be greatly 
appreciated. PS. if there is a cost involved for the source code 
please leave ddn address and local phone number for point of contact.

Thanks in advance from Heidelberg Germany, where the wine is fine and the
women are too!!!.

PS. We do Unix!!! for 117 MAcs and two vax's.
