My program reads serial from one port by using getc() from a byte stream and putc() to other serail port.  When getc() get 0x0A from byte stream , it will automatic add 0x0D infont of 0x0A when I use putc to printout.

How I can stop the automatic add 0x0D when it get 0x0A?

Are you sure it's doing that? Usually one needs to configure the terminal to interpret LF (0xA) as newline, maybe that's what you did?

I use my linux terminal with sniffer the serial port

jpnevulator --ascii  --timing-print --tty /dev/ttyACM0:SB9600d --read

and it add 0X0D when it get 0x0A

but thank to your advice. I have to use minicom -s to set my /dev/ttyACM0 first before I call jpnevulator again. Then, problem is solved.
