I have a DOS program that modifies the COM1 port. When I run the program from Windows 3.0 in enhanced mode the modifications fail to occur. The routine where the modification takes place is written in Assembler and linked in-line with the larger C progranm using QuickC. When I run the program in Windows 3,. in standard and real mode it works fine. What gives? Am I doing somehting wrong? Is a pif file necessary? Thank you very much! reilly@bnlux0.bnl.gov
