Hi, I am realy new to Delphi and I have a question.

I'm trying to make a program that will send some characters at COM2. This is
the code.

I get the error EVariantError with the message "Invalid variant type
conversion"

Please help me understand where is the mistake.

Thanks a lot.

Here's the code:

generic_write,0,0,open_existing,0,null);

You are using the wrong function to write to the com2 file! Define this:
var
    numWritten : integer = 0;

and use this function:

WriteFile(hcom, @ch, 1, @numWritten, nil);

or use pascal file approach for the com port too but i'm not sure it will
work:

var
    fcom : file of char;

AssigFile(fcom, 'COM2');
Rewrite(fcom);
Write(fcom, ch);
Closefile(fcom);
