在运行期，动态设定spcomm控件的Parity属性值即可。
如Comm.parity:=evenparity;

[Error] Unit1.pas(30): Incompatible types: 'TParity' and 'Integer'

好像可以了，我是这样改的，谢谢chll
Comm1.parity:=Tparity(none);
Comm1.parity:=Tparity(evenparity);
Comm1.parity:=Tparity(markparity);
Comm1.parity:=Tparity(oddparity);

我刚才也试了，好像
Comm1.parity;=even;也可以

你可以设一个变量来存贮：
comm_parity:TParity;
comm_parity:=even;
comm.parity:=comm_parity;
