Is it possible to use MATLAB on slave computer/device for communication to host computer via serial MODBUS (RTU)

Can I communicate with the host/master via serial port (MODBUS ASCII/RTU) using MATLAB on the slave computer, i.e. I need to wait for a request from the host/master, receive it when it comes and send back the requested data to the host. I found how this can implemented for MODBUS TCP/IP, but I did not find how to implement that for MODBUS ASCII/RTU (RS232, RS485). All MATLAB functions for serial port communication seem to be for the case when the code runs on the host computer. My MATLAB code runs on the slave device (processor/computer which controls the analytical instrument) and I need it to send the data when requested to the host (SCADA).
