From mboxrd@z Thu Jan 1 00:00:00 1970 From: dave@horsfall.org (Dave Horsfall) Date: Thu, 27 Nov 2014 07:48:39 +1100 (EST) Subject: [TUHS] What's with the DZ-11? Message-ID: I've seen a couple of less than flattering references here; what was the problem with them? At UNSW, we couldn't afford the DH-11, so ended up with the crappy DJ-11 instead (the driver for the DH-11 had the guts ripped out of it in an all-nighter by Ian Johnston as I recall), and when the DZ-11 came along we thought it was the bees' knees. Sure, the original driver was as slow as hell, but the aforesaid IanJ reworked it and made it faster by at least 10x; amongst other things, I think he did away with the character queues and used the buffer pool instead, getting 9600 on all eight channels simultaneously, possibly even full-duplex. -- Dave Horsfall DTM (VK2KFU) "Bliss is a MacBook with a FreeBSD server." http://www.horsfall.org/spam.html (and check the home page whilst you're there)
