Need one extra Line to work on macOS:

[cyba3r]

Hi :-)

Great work from your side!! To get this program running on Mac (Silikon) you need one extra line code. Otherwise you get an error:

"k5_receive: bad magic number" or "error 22 Invalid argument"

Function"int openport(char *port,speed_t speed)"

.....
cfmakeraw(&my_termios);
cfsetospeed(&my_termios, speed); <-Needed for MacOS
cfsetispeed(&my_termios, cfgetospeed(&my_termios));
....

Cheers

Thanks, it is also needed on Intel Mac

macos version: 14.4.1 (23E224)
Xcode Version 15.3 (15E204a)
gcc version 13.2.0 (Homebrew GCC 13.2.0)

PS: only /dev/cu.usbserial-xxxx work, not the /dev/tty.usbserial-xxxx

Hello, tried and tested. First it failed, then I compared the code.

The actual line that needs to be added is the third one:

.....
cfmakeraw(&my_termios);
cfsetospeed(&my_termios, speed); 
cfsetispeed(&my_termios, cfgetospeed(&my_termios)); <-- This is the actual line that needs to be added.

Confirmed that this patch works in macOS 14.4.1
