Difference between modes in serial instructions

[amindzo]

Hi, what's the difference between modes in serial instructions such as serin and serout? what's the difference between (for example) T2400 and N2400 and OT2400 and ON2400? when i should use them and in which situation and for what applications?

thank you

any answer?

Try reading the instructions for whatever language uses those terms.

Not the greatest amount of information I've ever seen in a post.
Try at least telling us what device you're using, and what language.

Like Nigel say, need to know what programming language you use...
Try this two link, will give you some info..

Hi, i use picbasic pro and PIC16F877A, i know the instruction but i don't know the difference between them(T2400,N2400,OT2400,ON2400).

i know the instruction but i don't know the difference between them(T2400,N2400,OT2400,ON2400).

T means when it sends a '1' the output is high. This is true logic that you would feed into an RS232 level shifter like a MAX232 for example

N means when it sends a '1 the output is low, this simulates RS232 logic levels where a '1' is represented by a low voltage level and a '0' by a high voltage level.

O means the output 'simulates' an open collector configuration, driving the line low, but letting it float high.

This is all explained clearly in the documentation. You should read it.
