Hi Freddy,

That works fine on my FreeBSD 5.0 system.

FWIW here are the avaliable options from tcp.h

#define TCP_NODELAY     0x01    /* don't delay send to coalesce packets */
#if __BSD_VISIBLE
#define TCP_MAXSEG      0x02    /* set maximum segment size */
#define TCP_NOPUSH      0x04    /* don't push last block of write */
#define TCP_NOOPT       0x08    /* don't use TCP options */
#endif

Have Fun!
Peter
