In article <952@aoa.UUCP>, I asked how to configure a kernel for additional
ptys.  I mistakenly interpreted (italic)"max n" in the manual as if it were
(bold)"max" (italic) "n", which led me to include "max" as a keyword in
the pseudo-device line in the config file.  Thanks for the responses.  I've
got it working now.

I can explain this mystery.  The file /sys/data/tty_pty_data.c contains the
following code:

	#if NPTY == 1
	#undef	NPTY
	#define	NPTY	32		/* crude XXX */
	#endif

The documentation clearly should say that the default is 32, not 16.

Thanks to all who responded.
