2400/8 = 300 . This 300 Baud send to 1 bit , upto 8 bit.

So kindly send me code for my work ... pls pls...

Solution 1

You can't - serial ports don't work like that because serial data doesn't work like that.
When you send a character, it goes out as a "formatted package" which consists of a Start Bit (always a zero), 5, 7 or 8 data bits, an optional Parity Bit, then 1, 1 1/2, or 2 Stop Bits (always a one). If your port is configured to 2400 baud, then you cannot transmit data which causes it to "look like" 300 baud data because you can't "force" it to lengthen the start and stop bits by a factor of eight.

You want to send 300 baud data? Set your port to 300 baud.

Don't you think it is a bit over confusing. :D

Nature of the beast! :laugh:
It's not really fair to say "You can't" and not explain why when it's a real limitation he can't work round.

It was my way of saying, I didn't get the point of it but you got 40 of them. ;P

Your question is no sense. It appear than you don't understand the basics of serial communication.
What you ask just do not exist. There is nothing like divide some bauds to get some bauds.
You should have a good lecture on the subject.
