Help using .OCX files with Delphi 2.0

I am trying to use .OCX files with Delphi 2.0 and it seems that Delphi
ALWAYS wants to make the variables 'variant'.  I have to write a
string to a method in an .OCX (mscomm.output) and it must be pchar or
unicode and not delphi string format.  So, how do I tell delphi that
'mscomm.output' is pchar or pwide instead of variant?  Please e-mail
me at li...@kirk.northernc.on.ca if possible because my news server
loses messages at times.  Thanks.
