that unit should only be used in certain specific cases... generally speaking,
it isn't needed for most code...

the libs are already written... all you have to do it use them and add your
code to manipulate the data sent/received as desired...

when i was going more pascal coding than i am now, i spent a good part of the
time stripping out my custom routines because they already exist in the
available libraries... i also spent a lot of time ripping out my custom ASM
code because it was easier to use the pascal versions that did the same plus
had more features than my speciality code did...

where i spent a lot of time writing a pascal version of the C time_t routines,
those were also ripped out because there are more and easier to use time
routines than what my lowlevel ones provided...

direct memory addressing like reading the BIOS serial and parallel port
addresses and writing directly to video RAM are not used any more... the OS
simply won't let you have access to the hardware any more... using the TP mode
does allow almost all old TP code to be compiled but you'll definitely have to
rip direct memory addressing stuff out and find other routines to replace many
commercial libs you may have used... some of those old commercial routines are
now open and already rewritten and included with FPC and/or Lazarus...
