CRead and CWrite

[RoboticsMan]

Hi

I am working on a project, where we use the CRead and CWrite commands to communicate with a pc through a serial connection. We experience problems with lost bytes, i.e. sometimes some parts of the strings sent from the pc are lost. I have found out that is caused by a input buffer overflow in the UART of the robot controller. This problem can be avoided if it is possible to enable hardware flow control (RTS/CTS) on the serial port of the robot. Does anyone know whether this is possible, and if so, how to do it?

Thanks in advance!

I don't know whether RTS/CTS lines are possible to control or not; you can try enabling XON/XOFF (software flow control) in both devices (robot and PC).

Your data string must not contain neither the XON nor the XOFF characters in order the communication to work properly.

Regards,
V.

You can adjust the buffer size in SERIAL.INI

It is correct that I could adjust the buffer size in the serial.ini file. But I think that the size of the buffer on the UART is the real problem, and as far as I know, this size is 16 bytes and cannot be adjusted.
