Some newer hardware does not have COM1 at all. It seems this isn't easy to detect, and so the best solution is just to use a maximum spins timeout. This is in fact what FreeBSD does already, and the "timeout" value of 256K unsuccessful spins is the same one they use (see "COMC_TXWAIT" definition). If the timeout happens once, then just disable serial or mark it as timing out and don't try again (unless we eventually load a settings file that specifies a new serial port.) Tested on a custom build of QEMU hacked to reply to all reads to the serial ports with zeroes (by just adding "return 0" to "serial_ioport_read".) Fixes #18561. May fix #19425.
Haiku
Homepage | Mailing Lists | IRC Channels | Issue Tracker | API docs
Haiku is an open-source operating system that specifically targets personal computing. Inspired by the BeOS, Haiku is fast, simple to use, easy to learn and yet very powerful.
Goals
- Sensible defaults with minimal configuration required.
- Clean, clear, concise code.
- Unified desktop environment.
Trying Haiku
Haiku provides pre-built nightly images and release images. Haiku is compatible with a large variety of hardware, but in case you don't want to "take the plunge" and install Haiku on bare metal, you can install it on a virtual machine (VM) instead. If you've never used a VM before, you can follow one of the "Emulating Haiku" guides.
Compiling Haiku
See ReadMe.Compiling.
Contributing
Haiku is a meritocratic open source project with a large variety of tasks. Even if you can't write code, you can still help! Haiku needs designers, (technical) writers, translators, testers... Get involved and help out!
