Bazaar(uppHub) thing:
i suggest - don't throw away Bazaar archive - it has a lot of usefull code.
I didn't for example found Serial package or non-bazaar FontSel(dialog)
in uppHub(maybe i overlooked something), which are mostly just copy/paste
packages - since all works out of the box.

For Serial bazaar package i just added this, to adjust a few things,
for linux, i am not sure if this is needed or how it's done.

  void SetWriteTimeout(dword ms){
    COMMTIMEOUTS ct;memset(&ct,0,sizeof(ct));
    ct.WriteTotalTimeoutConstant=ms;SetCommTimeouts(fd,&ct);
  }
  void SetTimeouts(dword msRead,dword msWrite){
    COMMTIMEOUTS ct;memset(&ct,0,sizeof(ct));
    ct.ReadIntervalTimeout=ct.ReadTotalTimeoutMultiplier=MAXDWORD;
    ct.ReadTotalTimeoutConstant=msRead;
    /*ct.WriteTotalTimeoutMultiplier=MAXDWORD;*/
    ct.WriteTotalTimeoutConstant=msWrite; SetCommTimeouts(fd,&ct);
  }
