You would be interested in this video, in which the vlogger installs the POSIX subsystem for Windows NT 4.0sp6 (after previously having tested the version for NT 3.1). It’s a summary of a livestream ...

Why did Linux standardise on RTS/CTS flow control for serial ports

Linux started as a hobbyist operating system. It was in no position to set any kind of standard. Instead, Linux implemented what hobbyists needed at that time. When Linux got popular, the convention ...

Why did Linux standardise on RTS/CTS flow control for serial ports

Serial port standards weren't. Obligatory XKCD. Different devices had different preferred handshaking lines. And even if all DCE worked the same and all DTE worked the same, you had situations of DTE -...

Why would email transmission change the 6-char sequence "0rom "?

I notice that the sequence 0rom is actually 5 characters. I wonder if the manpage intended to say something like >From E-mail software sometimes stores multiple e-mail messages together in a ...

Why did Linux standardise on RTS/CTS flow control for serial ports

The history is that Linux copied Unix. People at Bell Labs developed Unix. RS232 was specifically intended for modem interfaces. Unix naturally used AT&T RS232 modems to communicate through the ...

In what ways was the Windows NT POSIX implementation unsuited to real use?

Having tried to use it, I found it had a major fault that rendered it unusable. Delete file while in use did not function; and quite a few applications from the era expected this to work; with them ...

How can I get X11 to run under SVR4 on 86Box?

Very partial answer, but I already spend entirely too much time on it, so maybe this information helps somebody else. There are a number of collections of floppy installation disks for SVR4 available ...

In what ways was the Windows NT POSIX implementation unsuited to real use?

I was working on porting unix software to windows NT at the time. Strict POSIX was never a useful standard as it did not include network access or graphical outout. Unix systems that supported POSIX ...

Why did Linux standardise on RTS/CTS flow control for serial ports

The assumption in the question is incorrect. Linux has support for modem control lines like DSR and DTR, via the TIOCMGET and TIOCMSET TTY ioctl command. The relevant bitmask values are TIOCM_DSR and ...

Why did Linux standardise on RTS/CTS flow control for serial ports

As a rather old dinosaur (older than 60...) I can remember using V23 modems in the 80's. They were rather popular in France because they were the modem of the good old minitel. In short it was a ...
