binary text file transfer via serial port to FPGA

I am trying to transfer binary text file via virtual serial port to FPGA and receive the result after being processed in FPGA. I am using below code to do it.

a=serial('COM5','BaudRate',115200);

fopen(a)

fid = fopen('testfile.txt');

txdata = fread(fid,inf,'uint8','ieee-be');

%%uint8 = 8bit ieee-be = big endian

fwrite(a,txdata,'uint8');

fclose(a);

But I am getting error: unsuccessful write to comp port. Testfile contains binary matrix value. When I display txdata, it is giving some random value.

Please help!
