Installation. Minicom provides a text-based interface for sending and receiving data, and supports features such as terminal emulation, scripting, and file transfers. 0x55,0x18,0x03,0x06,0x01 but I am not actually convinced this is actually hex data or just a string conversion of what is being sent. I'm trying to use minicom (or any other terminal program available over ssh) to send and receive (and possibly log) very simple serial commands to my microcontroller. <string> can be: - regular text, The minicom source code comes together with two example scripts, scriptdemo and unixlogin. I want to ask how to simulate press ENTER & CTRL+Z in bash Can I write script like this? In Tera Term I use the Serial Port to send commands to the board in order to log in and run certain settings that I want. I've been able to open a port, send a command (using the "write" on /dev/ttyUSB0) and read the response (using "read" port). c#; string; sockets; Share. Minicom will automatically detect the file transfer. USART1_IRQHandler() is a handler for USART data. It is followed by a '\r'. If you specify a non-zero value, the hangup will be done by dropping the DTR line. See How do keyboard input and text output work? for more information. I am using minicom scripts to configure my uboot environment. stty -speed 19200 -f /dev//dev/ttyAMA0. ). So if you first start a data call with ATD1234 then you can after that call ends give ATDL to set up a new data call to the same number.
