>Description:
Running Oracle listener from an SCO ODT3 (3.2v4.2), the listener polls
for incoming flow using ioctl(..FIONREAD).
After Ktracing the problem, i found that flags definitions are corrects in IBSC2
but is only handled by 'IBCS2_I_NREAD'.
>How-To-Repeat:
runs any SCO compiled program using this ioctl form of polling.
>Fix:
file sys/i386/ibcs2/ibcs2_ioctl.c, v 1.6 1995/03/14 15:12:28 scottb Exp
line 628, add :
+ case IBCS2_FIONREAD:     <<<<<< This line
  case IBCS2_I_NREAD:     /* STREAMS */
	SCARG(uap, cmd) = FIONREAD;
	return ioctl(p, (struct ioctl_args *)uap);
