Using the latest f/w 1.6.5 we still see corrupted Tx data out serial ports.
The test case is simply sending approx. 1700 characters (32 lines of A-Z, a-z) to serial port 1 over LAN.
The 3th or 4th attempt shows corruption with previous message data.
The Tx data continues to be corrupted by old data if you send 100 or more space or CR .
Have to reset Wiz140 &/or drop connection (Putty) to clear the corrupted buffer.
Receiving from serial port seems to work okay.
We have worked around this issue with previous f/w by dropping connection (LAN) & restarting with every Tx message.
We don’t have this problem with any Moxa n-port servers.
