teraterm

Hi,
I am using Teraterm. I want to send a file to PIC on RS232. My definition is as follow:
#include <16F877A.h>
#fuses HS,NOWDT,NOPROTECT,NOLVP
#use delay(clock=20000000)
#use rs232(baud=9600, xmit=PIN_C6, rcv=PIN_C7)

I use send file from file menu, but it is not done successfully. Does anyone have any idea? Shall I set any configuration?

Regards

You didn't show us the rest of your program, which hopefully is short.
What do you do with the bytes after you receive them ? The 16F877A
has only a few hundred bytes of RAM available. The file must be
small enough to fit in the limited amount of RAM.

My guess is that your PIC program is probably not getting the characters
from the UART quickly enough and it's getting an overrun error and is
locking up. To clear the "lock up" condition automatically, add the
ERRORS directive as shown below. You'll still lose characters, but at
least it won't lock up.

Did you try by checking the "Binary Option" into Teraterm (into the file dialogue box)

Are you processing each group or packet of data sent? If yes, you might want to consider including a transmit delay before sending the next packet. Try starting small, sending only a few bytes and check if they are received correctly. Perhaps the PIC code is not interpretting the bytes as intended.

Cheers,
