I have configured the TRB245 Gateway for RS232 overIP as you could see in attached file.
Unfortunetly, I cannot connect to modem from LAN. When trying from telnet on the port, I doesn't have any error message, it seems to be connected but there is no message and I can't input any command. Only a dark windows with a white blinking point.
When I try to connect with a Third part python program, I got "None" message. Same program works perfectly with Lantronix Modems (see product description https://www.coniugo.de/tl_files/dateien/downloads/datenblaetter/GSM-Modems-EN/Datasheet_LTE_Modem_USB_LAN_RS232_CAT-4.pdf).
Please, I need help to connect modem through RS232 OverIP from LAN and execute USSD commands and results.
