read and write in serial port

[neda]

If I understand the information on serial break correctly, you are getting a sort of data timeout on the line.
This is a hardware thing: http://ltxfaq.custhelp.com/app/answe...erial-break%3F

Maybe the device you are connected to can't keep up or is using different settings?
