*đây chỉ là file do người dùng định nghĩa thôi bạn.
ví dụ nhé :
bạn tên : Nguyễn Văn A , giới tính : nam , sinh ngày : ... , quê quán:.... : , lớp :.... , mssv : ....
Vậy thì nhà trường chỉ cần biết MSSV là có thề biết thông tin chi tiết về bạn.
Và khi bạn lên phòng đào tạo xin bảng điểm thì bạn chỉ cần ghi MSSV chứ không
cần phải dài dòng nữa..
*khi bạn khai báo #use rs232(baud=9600,parity=N,xmit=PIN_C6,rcv=PIN_C7,bi ts = 8)
thì c.trình tự hiểu địa chỉ của XMIT , RCV
