oTerminal is an universal and easy to use terminal program for ethernet communication (TCP/IP) and serial ports. With oTerminal and a standard ethernet to serial converter, it is easy to connect serial devices with different baud rates. It is also possible to connect ethernet devices that use a low level binary protocol such as Modbus. To connect direct to a RS232 of RS485 port, a serial (usb) device adapter / converter is needed. If you have a problem using oTerminal, please don't write a review, but send us an e-mail so we can help.
