Réf. : RE: Send data on serial port!
I have do the same with no problems on a devboard LX
- you can see the hwtestserial.c source file given with the DEV KIT
- you must open the device with open (not fopen)
- If you send the character to a printer ,you need probably to send \n to
- do you use a line analyser to control the character ??

I've done that but I still need to send '\n' to have the character sent
from the send buffer. Any other idea?

Make sure you set the terminal settings to "raw" on both the
sender and the receiver, e.g. by using the cfmakeraw() function.
See 'man cfmakeraw'

> I need to send data character by character over a serial port(/dev/ttyS0)
on a LX board. To achieve as high speed
as possible I want to send as little overhead as possible. When I send data
now I always need to add a line feed to
have the data sent immediately. Is it possible to send just a byte without
a line feed?
