Does anyone have recommendations for inexpensive IP/ serial adapters that would work to troubleshoot occasional boot issues? A way to put some old Cisco gear to use perhaps, although I do not see any way to do that at the moment- Thank you- Brian

That particular one uses custom cables. I'm such a yutz - I meant Portmaster 2e. Check for the one that has all the ports on it already unless you want to buy the custom cables from Portmaster. This one is similar to what I mean but keep looking for one with all serial ports and a better price: http://cgi.ebay.com/Livingston-Lucent-Portmaster-2e-10-serial-10- ISDN_W0QQitemZ150354234383QQcmdZViewItemQQptZLH_DefaultDomain_0? hash=item2301cf8c0f&_trksid=p3286.c0.m14 Mike On Aug 4, 2009, at 8:15 PM 8/4/09, Brian wrote: > http://cgi.ebay.com/PortMaster-PM25-Lucent-Livingston- > Communications- > Server_W0QQitemZ390051927301QQcmdZViewItemQQptZCOMP_EN_Routers? > hash=item5ad0e81505&_trksid=p3286.c0.m14 > > is there anything I should be aware of re: rivers/ adapters/ > cabling etc? > > that's cheap enough to be usable for fun and learning/convenience. > > thanks! >(Continue reading)

I am trying to troubleshoot boot issues from remote, after a power blip, working with non-tech people, for one time too many : ) Nothing mission critical but looking for nice/ convenient/ I don't have to do this again.

What about some old DECServer 200MC's? MOP boot them and they should give you 8x serial ports, or some multi-port stallion card with minicom sessions that have separate config files pointing to various ttySx's? -- -- Al Boyanich adb -w -P "world> " -k /dev/meta/galaxy/ksyms /dev/god/brain On Tue, 4 Aug 2009, Brian wrote: > > On Aug 4, 2009, at 8:23 PM, Mike Hebel wrote: >> On Aug 4, 2009, at 6:04 PM 8/4/09, Brian wrote: >>> Does anyone have recommendations for inexpensive IP/ serial adapters that >>> would work to troubleshoot occasional boot issues?

What exactly are we trying to do here? if you are troubleshooting boot issues, why don't you just run a null modem... if you want network connectivity via the serial port, set up a ppp server over the null modem post boot. am i missing something?

I suspect by the sound of it, he wants a central machine with multiple serial ports hanging off it to control 'n' machines. But, perhaps I've mis-understood also. -- -- Al Boyanich adb -w -P "world> " -k /dev/meta/galaxy/ksyms /dev/god/brain On Tue, 4 Aug 2009, Kenneth P.

Is http://www.monoprice.com/products/product.asp?c_id=103&cp_id=10311&cs_id=1031104&p_id=2067&seq=1&format=2 a stupid suggestion for this? And with hubs you could essentially have 127 comm ports per root hub. Or do the extra hubs count as devices? Can't remember, but you'd still be able to connect a lot. By the original mail it sounded like you just needed a way to manage multiple switches (or other network appliances) and these would make sense to me. ----- Original Message ----- From: "..I'd rather be coding ASM!" <uridium <at> deviate.fi> To: "Kenneth P.

What used to be called a "terminal server", like the old Spider Atom, where you could telnet to a port on a server, and be presented with a connection to whatever was hanging off a particular serial onthe server. You can get similar functionality with "termnet". -- -- In fourteen months I've only smiled once and I didn't do it consciously
