In some cases, there is a need of putting a limit on the size of characters that can be typed in a textarea. So in that case, we can use maxlength attribute to control the number of characters entered in a textarea.
The HTML <Textarea>maxlength attribute is used to specify the maximum number of characters enters into the Textarea element. Attribute Value: number: It contains single value number which allows the maximum number of character in Textarea element. Its default value is 524288.
To ensure line lengths don't exceed 80 characters, the CSS max-width property can be set using font-relative lengths of around 70ch or 34em (note that this value will need to be adjusted slightly up or down depending on the font used).
This is not standard, but it works in many browsers, test it.

<TEXTAREA NAME="HARD" COLS="72" ROWS="5" WRAP="HARD">
Setting wrap to hard makes it send new lines to the server. Setting it to soft only breaks it visually.

No need to use javascript for this. There is a HTML attribute built into the <textarea> tag.
See some documentation here.
example for your use
<TEXTAREA NAME="HARD" COLS=72 ROWS=5 WRAP=HARD></TEXTAREA>
Using a HARD Wrap actually sets carriage returns when the line is wrapped.
