SLIP dialup problems.

[Steven Wu]

I have a Sparc 2 and a Sun 3/50, both running SunOS 4.1.1. I have already
rebuilt the kernal and put the CSLIP driver in them. The problem I have
right now is, I have to use modem dialup to connect these two machine and
the only software I have is a modified tip program. which comes from the
SLIP parallely.

The problem I have is the tip doesn't work quit well, I have a message
like:

  Lock open: no such file or directory
  all ports busy

Could anyone tell me what the problem is?  Thanks for your help.
