'outp' and 'inp' (or outportb, inportb depending on what compiler you use) are MS-DOS
compiler intrinsics that translates directly to assembly instruction 'out' resp. 'in'.
I haven't looked at dosemu's source but I'd be a bit suprised if it didn't emulate
the IO-ports 0x3F8 and 0x2F8 considering that _all_ programs use these directly since
the BIOS and system support for serial kommunication (int 0x14) is so poor.
