== RS485 becomes unresponsive occasionally ==
Just wanted to report on potential firmware issue, so hopefully developers can address it.
We are using RUT955 router (FW: RUT9XX_R_00.06.04.5) for remote (OpenVPN tunnel) access to Modbus devices on RS485 network. All is working fine, but a couple of times RS485 became unresponsive, i.e. we were getting timeout on reading our remote RS485 units (web access to the router did not have any issues). The router's RS485 functionality was recovered remotely - in one case by resetting the router and in the other case by disabling/re-enabling RS services.
Is it an already known issue and is it going to be addressed in the firmware at some stage ?
While recovery is possible and relatively easy for us, it's not something nice to pass to our end customers...
N.B. The router is configured for scheduled re-booting every night.
