Error in transmission of hexstring data on serial port [message #1796822] Fri, 19 October 2018 12:24 Go to next message

When I use TITAN to transmit 'hexstring' data through serial port, the receiver accepts it through serial port, and the receiver will appear superfluous zero data between two frames, which causes the matching failure with the ideal data acceptance. What may be the reason for this phenomenon?

Thank you for your answer!

Hi,

Have You set the terminating character to the same on both ends in the config file?
e.g.:

[TESTPORT_PARAMETERS]
...

*.SerialPort1.EOLChar := "\n"
*.SerialPort2.EOLChar := "\n"

Hello
Thank you for your answer.
The receiver is not a TITAN but a real serial port. The separator of each frame is" 0x7e". The receiver will do a frame breaking process, but the data will receive an additional 0. For example:
the TTCN3 code is

SerialPort2.send('7eff7e'H)
SerialPort2.send('7e107e'H)

the receiver will receive 0x7eff7e0000007e107e000000
