Or if you've got a PC-based RS232 Navtex aerial (like the Nasa PC Navtex receiver), then you'll need a generic serial terminal application.

I use goSerial from www.furrysoft.de

Thank you very much for the advice and the sources.
I come back on a three weeks cruise between French Riviera and Corsica and my S15-N NAVTEX receiver from SILVA (only 78 euros) works very well with goSerial ans a KEYSPAN adapter.
