Hi everyone,
What is the difference between console-based and Xwindow-based application?
Can I say the application working well in Xwindows can work in console?
Can I say the application working well in console cann't work in Xwindow perhaps.
Eg, ncurses is console-based and Imlib2 is... (4 Replies)
Hello!
I am working on an application which reads environmental instruments which have serial ports. The application requires a serial port to be present to talk to the device (i.e. /dev/ttyS0 ). In some instances the environmental devices will be 100's of yards away from the computer, so a... (5 Replies)

Hi,
I have a external board connected to my serial port. I need to execute "shutdown -r now" command when system boot up. When system boots up it requires a username ans password. Then I need to run my command. I can use rc script but that is rebooting system before it asks for username and... (0 Replies)
I am looking to make the switch from a Windows based network to a Linux (preferably Ubuntu, because I used it the most) based one. Currently the network includes a Windows 2003 server which acts as a domain controller and file server, a network shared printer (Canon 2300N) and 7 clients running... (2 Replies)

slip
SL(4) BSD Kernel Interfaces Manual SL(4)NAME
sl -- Serial Line IP (SLIP) network interface
SYNOPSIS
pseudo-device sl
DESCRIPTION
The sl interface allows asynchronous serial lines to be used as IPv4 network interfaces using the SLIP protocol.
To use the sl interface, the administrator must first create the interface and assign a tty line to it. The sl interface is created using
the ifconfig(8) create subcommand, and slattach(8) is used to assign a tty line to the interface. Once the interface is attached, network
source and destination addresses and other parameters are configured via ifconfig(8).
The sl interface can use Van Jacobson TCP header compression and ICMP filtering. The following flags to ifconfig(8) control these properties
of a SLIP link:
link0 Turn on Van Jacobson header compression.
-link0 Turn off header compression. (default)
link1 Don't pass through ICMP packets.
-link1 Do pass through ICMP packets. (default)
link2 If a packet with a compressed header is received, automatically enable compression of outgoing packets. (default)
-link2 Don't auto-enable compression.
DIAGNOSTICS
sl%d: af%d not supported . The interface was handed a message with addresses formatted in an unsuitable address family; the packet was
dropped.

HISTORY
The sl device appeared in NetBSD 1.0.
BUGS
SLIP can only transmit IPv4 packets between preconfigured hosts on an asynchronous serial link. It has no provision for address negotiation,
carriage of additional protocols (e.g. XNS, AppleTalk, DECNET), and is not designed for synchronous serial links. This is why SLIP has been
superseded by the Point-to-Point Protocol (PPP), which does all of those things, and much more.
