Hi, I want to send commands to ttyO1 (serial port on an embedded system). The commands are one line each and terminated with CRL/LF (aka "DOS").
Since this will be done from a batch script, it should be possible via commandline tools and non-interactively. The serial port is already setup up the right way. I tried echo -n"blablabal\x0a\x0d" , which was accepted (no error) but does not acchieve anything. The command was cat'n'paste from the documentation of the manufacturer of the chip (a GPS receiver module). I tried different commands. All were directly send to /dev/null inside the chip it seems... Is there any other simple straight forward method of writing successfully to a serial port (only RX/TX are connected) without dealing with minicom or advanced serial port programming in C? Thank you very much in advance for any help! Best regards, mcc
