Page 14: B Setting Up Cellular Packet Data Connection
This section describes how to set up a packet data connection on Windows 10 and Linux using the operating system’s TCP/IP stack and EVK-R6 and EVK-L6. This is also referred to as a dial-up connection (PPP), which is not ideal in the throughput performance perspective but it may be good enough for many applications that do not require high data rate connection. - Page 15 EVK-R6 and EVK-L6 - User guide Tick “Don’t detect my modem” checkbox. Then click Next. Select Standard 33600 bps Modem and click Next. Select the COM port to use for data communication and click Next. This is the COM port on which the modem will be installed.
