@TheOneDoc @freya I can’t actually view that website because it’s behind a cloudflare captcha and even if I get past that there’s a popup that reappears every time I close it with a link to something that gets blocked by ublock origin, but there’s more than one pinout. A null modem cable just has rx and tx swapped (although which exact pins are swapped can vary)

If you’re a Codeberg e. V. member, please vote in favour of the reform to the association’s internal electoral systems. They will make future votes, whether for policies or for elected positions, fairer and more representative when more than two options are on the table.

@alda I mean the nominal voltage of most lithium ion batteries

@kemona_halftau same

"There are colors that I want to show you, but I can’t. They exist in the real world. You probably saw some of them today, but I can’t show them to you on a screen. A digital photograph can’t capture them, and your screen can’t display them. No game you’ve ever played has contained them. Unless you have specialized equipment, they are entirely absent from the digital world.

Most of them are cyans."

@alda I think usually when selling power banks in mAh they use the voltage of the battery (3.7V) rather than the output voltage

@alda I wish they would sell them in watt-hours or at least specify the voltage if using amp-hours

@TheOneDoc @freya null modem doesn't specify the pinout, it just means it's a DTE

good morning/afternoon

@freya my suspicion continues to be that it's a weird pinout and I just didn't connect it right, but I haven't been able to find any information about what the correct pinout is.

I might end up buying the overpriced IBM serial adapter, I can at least return it if it doesn't work. (I also can't do anything about it right now, I'd need to wait until I get home in a few days)

I should really sleep now, good night!

@freya it was initially configured for an HMC but I reset the FSP from the ASMI web interface before doing this (it was also sold to me with an unknown ASMI password initially, which I reset with a jumper on the FSP)

@freya there's an ASMI web interface that I can access via the FSP ethernet ports where I can set the baud rate and I made sure all that was right. I don't have an oscilloscope (I should get one) but the documentation says it's serial and I measured 15V with a multimeter (which seems right for RS232 and definitely not Ethernet)

@freya I'm just trying to get it to boot anything at all. It reaches status code AA00E1B0 (meaning "Waiting for the user to select language and keyboard."), but there is no output on the serial port and I don't have an HMC so I can't access the serial port that way.

I think I probably just didn't connect to the serial port correctly (either that or there's something actually wrong with it). It's one of those 8P8C ones but it doesn't seem to be any of the standard pinouts (I tried EIA/TIA-561 and Yost). There's an official IBM adapter that might work but it's quite expensive for a passive adapter.

@freya they call it IPL on Power Systems too (mine is a 9008-22L)

@freya so, do you have any experience with IPL devices (of the IBM kind)? (I have one and it won’t IPL)

I love having >100% uptime

@Jes @kemona_halftau on pissnet it was always the one windows server that had a clock that was consistently off by a few seconds (IRC requires accurate time on servers because timestamps are used to resolve nick/channel collisions)

@kemona_halftau it looks weird

@niko the fact that it's more than a quarter of people does surprise me (I have never knowingly stolen from self-checkout)
