cu program?

[Larry W.Irwin Sr. <riverw@bigriver.net>]

  Hi,

  I have finally built a small home lan and want to leave my modem
connected to the server machine. I found a HOWTO on this subject in
the doc-linux package. The following perl script was listed as one
method of routing pppd from one machine to the other.
-------------------------------------------------------------------
#!/usr/bin/perl                                                              
select((select(STDOUT), $| = 1)[$[]);                                        
select((select(STDIN), $| = 1)[$[]);                                         
exec 'cu -s 115200 -l /dev/ttyS0';                                          
die '$0: Cant exec cu: $!\n';                                                
-------------------------------------------------------------------
  I cannot locate the cu program. Can someone point me in the right
direction?

Thanks,
Larry
