how to generate specific data with certain data rate

i want to generate data ( 01001111010001 ) with data rate (200kb/sec ) . i ask how to generate this data with this certain data rate

[Walter Roberson]

Is this a Simulink question? Or is it a question about outputting to a serial port? Or through a digital to analog convertor? Or through speakers ? Or ... ?

i need to generate this data to transmit with usrp device which connect to pc by usb .( i use usrp to send data wireless in radio frequency ) Thanks for attention mr Walter Roberson . and i wait your answer ?

Fixed-rate data cannot be transmitted by USB: USB is not designed for it. At least not if you need reliable data transfer to the USB-connected device: if you are willing to use unreliable transmission mode then USB is designed to allow "bandwidth reservation".

Unfortunately, MATLAB does not have any interface to that level of USB control.

Does the USRP device appear as a virtual serial port to the device manager? If it does then those transmissions are considered unreliable and there is no way (that I know of) to do bandwidth reservation for virtual serial ports (certainly not within MATLAB). Bandwidth reservation in USB is typically used for audio or video
