I still have an lmc(4) T1/DS1 PCI card sitting in a static bag, but LanMediaCorp was acquired by SBE Inc, which in turn sold off their hardware business to One Stop Systems Inc. OneStop's OSS-PCI-1T1E1LP (http://www.onestopsystems.com/communication_wan_a.php) appears to be the same design, slightly smaller to fit on a low-profile card. (The original LMC cards were regular-height PCI cards IIRC.) OneStop appears to still make this card, a 4-port PCI sibling, and a 4- port PMC sibling. They explicitly state that "open source drivers are included", although they list Linux, NetBSD and FreeBSD. At the time, I was one of only I think 3 people worldwide using this card in OpenBSD, but I can tell you that Chris Cappuchio's driver was rock-solid (once you got it working at all - T1 configuration isn't quite plug-and-play). I'd be willing to bet that the new (single-port) cards still work with the lmc(4) driver, or that the driver would require minimal tweaking to function... the driver hasn't changed much in 4 years, and I doubt the card has either. I do note, however, that it appears the lmc(4) driver was re-merged from NetBSD back in 2005, whereas I was using ch...@dqc's original port from 1999. In fact, revs 1.3 and 1.4 in Feb 2000 were AFAIK due to my bug reports :-) The November 2005 CVS commit log entry of "also attach on LMC cPCI HSSI cards" for if_lmc_obsd.c v1.18 would lead me to believe that the newer PMC cards would also be supported, since LMC never made any of those - it was an SBEI product by then. Anyway, I can sell/rent/lend the card I have (an LMC1200, I think) to anyone who wants to test it out. (Er, assuming I can find it, anyway.) Alternately, there are several ways to get a V.35 serial signal from an OpenBSD box to an external T1 CSU/DSU. See www.blackbox.com for plain old rs232-to-v.35 converters, among more intelligent equipment. -Adam Thompson <athom...@athompso.net>
