[comp.protocols.tcp-ip] SLIP dialing problem.

stevew@helios.unl.edu (Steven Wu) (04/24/91)

  I am trying to set up the communication between a Sun 3 and a Sparc
2 through CSLIP, and both machines are running SunOS 4.1.1. I
reconfigure the kernal and run the slattach on both machine without
problem (I think). Since I need a dialing program, I compile tip which
comes with SLIP-4.0 and find the tip doesn't working.

  The following messages are what I get when I run tip:
	/dev/ttya file does not exsit
	all ports busy

  or sometime, they are:

	lock file ...
	all ports busy.

  Can anyone give me any suggestion?

  Thanks for your help.
