It looks like you have to send single numbers in sequence, like 242 followed by two numbers less than 128. Below is a patch that should do that.
At least [midiout] actually sends the message. For me [midiin], on the other end of the cable, outputs 242 and the right outlet is always 2. I don't know where the data went.

Actually now I do. In the source code s_midi.c, the function sys_dispatchnextmidiin():
                /* other kinds of messages are just dropped here.  We'll
                need another status byte before we start letting MIDI in
                again (no running status across "system" messages). */
            case MIDITIMECODE:     /* 1 data byte*/
                break;
            case MIDISONGPOS:       /* 2 */
                break;
            case MIDISONGSELECT:    /* 1 */
                break;

Okay, that's perfect.
All info are indeed in source files.
We can even send MTC code with 48 packets that contain 241 followed by one argument, but it seems very complicated to set up with pd patches.
