we struggle with establishing communication with device connected to RUT955's RS232 port:
PC [currently connected to router via WIFI] [sends specific request via TCPIP to device] > RUT955 < [RS232] device
PC [should receive response via TCPIP from device] < RUT955 < [RS232] device
We can communicate with device directly via RS232, so that the requests used/sent are valid.
We've tried to use Hercules/.NET libs to check communication:
A. When we connect loop-back connector to router's RS232 port (no leading zeros turned off), we receive couple of meaningful bytes in 64*1024 bytes long response (the tcp buffer is then 64*1024?)
B. When we connect device to router's RS232 port (no leading zeros turned on/off), it does not evince signs of received request and neither we don't receive any response in network stream
Is there any special configuration/approach needed to successfully establish a connection and communication with our device?
We'll appreciate any suggestion, tips&tricks, remote support.
