Speech recognition robot project

[jyothi1]

HI sir,
right now I doing speech recognition robot project.For that I am learning Matlab I am very new to this subject.I want to write program for serial communication in matlab.Actually I have written program. but I am getting an error as (? Error using ==> serial.serial at 62
The PORT must be specified.).In my program I used comport. Even though that error is coming.My program is as below.s = serial('COM2');
printf(s,'RS232?');
data1 = fscanf(s);
data = 9600;0;0;NONE;LF
C = textscan(a, '%d%d%d%s%s','delimiter',';');

[br, sfc, hfc, par, tm] = deal(C{:});

fclose(s)

I tried, but I did n't get where I did mistake.Can anybody please help me.

Thanks,
Jyothi.

The error you are receiving is due to the fact that you did not specify the port as an argument when initializing the serial object. To fix this, you can either explicitly assign a port before creating the serial object: port = 'COM2'; s = serial(port); or, you can pass the port as an argument when initializing the serial object, like so: s = serial('COM2'); Hope this helps!
