How to use PPP protocol over serial port?
I also presume that I can skip the PPP part and redirect somehow (make a virtual adapter in linux side) that will exchange packets over serial line in a proprietary format, eventually helped by flow control and or other GPIOs tied to my SOC but I feel that I am re-inventing the wheel.
Can a PPP connection work as a dial up?
You need to read the “PPP Howto” and setup PPP in both ends and it will work as an old 56k dial up connection. Thanks for contributing an answer to Stack Overflow!
What do you need to know about PPP protocol?
If the above is happening, you need to make sure you have someone to dial to, like a server with a similar setup to answer “the call”. You need to read the “PPP Howto” and setup PPP in both ends and it will work as an old 56k dial up connection.
Can you use PPP on a Linux box?
It’s easy to get to work on mbed-supported boards AFTER following the instructions on how to set up PPP networking on Windows. (Did not test it on a Linux box) Depending on your application, it might indeed be simpler to define your own protocol to transfer data between your WIFI SOC and a Linux box.
Can a serial port be moved to a modem?
If you have devices on standard serial ports that share an IRQ with your modem you are going to have problems. You need to make sure that your modem serial port is on its own, unique IRQ. Many modern serial cards (and better quality motherboard serial ports) allow you to move the IRQ of the serial ports around.
Where are the serial ports on a motherboard?
Many modern serial cards (and better quality motherboard serial ports) allow you to move the IRQ of the serial ports around. This shows a serial port on IRQ4 (a mouse) and a serial port on IRQ15 (the permanent modem based PPP link to the Internet.
How to configure PPP as a layer 2 protocol?
We will perform simple PPP configuration using two routers shown in Figure 12-5, the same internetwork used for HDLC configuration. Let’s now configure R1 and R2 to establish a point-to-point serial link using PPP as the Layer 2 protocol. Enter configuration commands, one per line.
Do you have to configure slip to use PPP?
In order to use SLIP or PPP, the access server must be configured with an IP routing protocol or with the ip host-routing command. This configuration is done automatically if you are using old-style slip address commands, but you must configure it manually if you configure SLIP or PPP via the interface async command.
What’s the difference between slip and PPP encapsulation?
SLIP and PPP define methods of sending Internet Protocol (IP) packets over standard RS-232 asynchronous serial lines with minimum line speeds of 1200 baud. Using SLIP or PPP encapsulation over asynchronous lines is an inexpensive way of connecting PCs to a network.
