I tried the auxinout (whatever) unit described in the manual, but it didn't compile even though i zillionchecked it for typingerrors. Therefore I tried another may. I used the exec procedure to run the MS-DOS MODE command for initializing the port. That worked in the UNISYS 286 in which i developed the program BUT, it didn't work in a UNISYS 386. What simply happens is that the program doesn't write anything to the port and it gets stuck. I also tried the DOS command COPY file.txt com1: That worked in the 286 but 386 gave error message device fault error etc. What went wrong ?
