Serial data problem

[The Master]

Hi. I have a loop which checks pir1.5 to see if any serial data is available. If it is then it loops to get it. Im inputting 18 characters at a time but the last few get missed off. Its random how many but always 1-3.

To start with i would like to know is there a limit to how many characters can be stored in the buffer before it starts losing info?

Depending the way you implemented it, unless your Oscillator speed and/or baudrate settings are not right, i can't figure out what's wrong.

EDIT: but i already experimented some weird stuff with cheap USB-to-Serial adapters...

Does it matter if there is a slight delay before i start getting data from the buffer?

Silly question.

            if rcsta.1=1 then
                rcsta.4=0
                rcsta.4=1
            endif

Does that empty the buffer?

[mister_e]

nope that clear the overrun error. If you want to clear the buffer, you need to read RCREG 'till RCIF flag is cleared.

TempVar Var Byte
RCIF var PIR1.5

WHILE RCIF 
    TempVar = RCREG
    WEND

Hmm. I am running that too but only once all the data i want has been received. I dunno.

Ive uploaded the code. Sorry its so long and confusing.
