I'm trying to read a serial port using cat, but I get absolutely nothing, usingcat /dev/tty.usbserial-FTZ29YKMI'm assuming that even if the baudrate is wrong, I should at least get some garbage data.  However, it works if I try to open a screen session with: screen /dev/tty.usbserial-FTZ29YKM 115200I want to use another utility to simultaneously write to the serial port, so I can't just use screen.  How would I make cat, or some similar utility, work?
Reading serial port using cat gets me nothing, but screen works?
osx;serial port
