💖 dahdi_hardware — the manual page, but make it make sense 💖

okay bestie, this is dahdi_hardware, and it lives in section 8 of the manual (the sysadmin corner 👑), shipped as User Contributed Perl Documentation. She's a little Perl script whose whole personality is "what DAHDI hardware is plugged into this box rn."

✨ NAME ✨

dahdi_hardware — shows Dahdi hardware devices. that's it, that's the job 🫶

✨ SYNOPSIS ✨

dahdi_hardware [-v][-x]

🎀 OPTIONS 🎀

  • -v — verbose output: show spans used by each device etc. Currently only implemented for the Xorcom Astribank. (so don't come for her about the other drivers, she said what she said 🙈)
  • -x — show a disconnected Astribank unit, if any.

🦋 DESCRIPTION 🦋

She shows you all the Dahdi hardware devices, no cap. Devices get recognized according to lists of PCI and USB IDs living in Dahdi::Hardware::PCI.pm and Dahdi::Hardware::USB.pm. For PCI it's possible to detect by sub-vendor and sub-product ID as well — signature behavior, love that for her 💅

The first output column is the connector: a bus specific field that shows where this device is. like, geographically, where is she 👀

The second field shows which driver should handle the device. A - sign marks that the device is not yet handled by this driver. A + sign means the device is handled by the driver. it's giving vibe check for your kernel modules fr fr.

For the Xorcom Astribank (and in the future: for other Dahdi devices) some further information is provided from the driver. Those extra lines always begin with spaces — that's how you know they're bonus lore and not a new device 🌸

ok notice how the + vs - flips once the drivers show up? that's the whole drama of this page. main character energy from a single character. iconic. ⭐

SEE ALSO — nothing extra to see here bestie, this page keeps its circle small 🎀

and that's the whole page!! this one's from perl v5.40.1, dated 2026-06-15, and it's filed under DAHDI_HARDWARE(8). go check your hardware, you got this 💜💅
