They are really wonderful.
I have a further question which is about voltage converters. I remember that it is necessary to use a voltage converter like MC1489 to convert TTL logic levels to RS232 voltage level. Does max232 handle with it?

That's the job of those max232,

Not sure what you mean...post an example of what you want and/or what you actually get...

the output is formatted

And again, is that what you want and can't get or what?
If that's the output that you want, you have to write that code yourself, using spaces, blank characters, whatever...SEROUT doesn't do that for you.

so you cant locate cursor as with small lcd

It's not shown in the PBP manual, but the basic ASCII character set has things like 'backspace', 'forward space', 'newline', etc. in it.
Do a search and I'm sure you'll find a million hits with ASCII tables and with values and explanations (i.e. 10 = next line, 13 = carriage return, 32 = space, etc).
And using various variations of SEROUT/SEROUT2/HSEROUT, etc., you can easily format a serial output to your liking.
