Thanks a lot guys. The VI can communicate with the virtual port now. A tip for anyone else trying simulate a COM port with a virtual instrument, pay attention to the correct syntax of the commands, and especially the termination characters, like <CR> and <LF>.
This advice applies to instrument communication in general.
