so far so good
after a lot of fruitless searching for the right answers i took the liberty to change the makefile_win.
$(VIS_CPP_PATH)\lib\libc.lib \
$(VIS_CPP_PATH)\lib\oldnames.lib \
$(VIS_CPP_PATH)\lib\kernel32.lib \
$(VIS_CPP_PATH)\lib\wsock32.lib \
$(VIS_CPP_PATH)\lib\winmm.lib \
i did away with the ones above.
$(PD_INST_PATH)\bin\pthreadVC.lib \
$(PD_INST_PATH)\bin\pd.lib
these 'local' ones i took from one of the latest Vanilla's (46.7).
no compile errors!
replacing the old comport.dll in pdext 43.4 with the new-compiled one: TADA it seems to work.
data is coming through, and no rxerrors.
minor point probably: i don't get a console message when a port is opened succesfully. the close message disappeared also.
more extensive testing/use will follow in the coming days.
thanks, rolf
