All i want to do is write 8 bit binary data out a serial port exactly as i specify it. you can use multiple serial send blocks at a time to send data to a specific serial port. the block sends data from the model to the serial port during the model's run time. the configuration and initialization occur once at the start of the model's execution. The serial send block configures and opens an interface to the specified serial port. i have seen some information on doing text through a serial port, mostly where arbitrary length data is returned at undetermined times. there is also a kermit send to the device as well. This needs to be done through a serial port (till the device is updated). all these things would make it extremely bothersome to make use of the sz rz tools on the nearby part with a plan like screen that will not have. Linux send binary data to serial port serial port using if that will not occur, you can still select the send document using zmodem (or upload file.) function personally from your terminal emulator. sfd = open (serial port, o rdwr | o nonblock) how do i configure the port to work in binary mode? thanks for helping. ![]() it seems to me that the port is configured to work in text mode, not in binary. I am sending binary data over a serial (rs 232) port. in the first terminal you cat everything from the device, e.g cat dev ttys0 in the other terminal, you can send arbitrary hex characters and text to the terminal e.g. All you have to do is open two terminals. note: use stty to configure serial port appropriately. file.bin is binary file, dev ttyps0 is device representing serial port. from the command line, for example: cat file.bin > dev ttyps0. behavior not depends on clocal or crtscts i use. none of this work: hw control not work at all, data transfer just stops (often at middle of byte when space state on txd stucks!) and never continues after release of busy. At other hand, i try to use cat file > dev ttys5, along with stty f dev ttys5 clocal or stty f dev ttys5 crtscts. ![]()
