Dampure" Organization: K2C Limited X-Mailer: Mozilla 4.05 [en] (X11; I; FreeBSD 3.0-CURRENT i386) MIME-Version: 1.0 To: FreeBSD-current@FreeBSD.ORG Subject: Current values of TTYHOG and RS_IBUFSIZE Content-Type: text/plain; charset=us-ascii Content-Transfer-Encoding: 7bit Sender: owner-freebsd-current@FreeBSD.ORG Precedence: bulk X-Loop: FreeBSD.ORG Over the past few weeks I've had several instances of userppp disconnecting a connection w/o particular reasons on bleeding edge -current. The only change on the box was the recent addition of a Hayes ESP card (I connect via ISDN), so I checked the archives for possible issues. Way back in 1996 (23 Nov), Brian Litzinger posted a follow-up to "Hayes ESP and interrupt-level buffer overflow" and advised altering the following constants : In /sys/sys/tty.h: TTYHOG Change to 4096 In /sys/i386/isa/sio.c RS_IBUFSIZE Change to 1024 I applied the above and haven't had any problems since -- in fact, it seems the connections are _much_ faster. Can anybody confirms whether these changes are valid and, if so, can we include them in -current (#ifdef'd via COM_ESP, of course)? Oh, on a completeley different subject, has anyone experienced problems connecting to Altavista (http://www.altavista.digital.com) recently? connection stay in ESTABLISHED state, nothing else happens. Works okay from work via a SunScreen... Best Regards, Pierre Y. To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-current" in the body of the message
