NAME

       m6pack - Attach multiples 6PACK interfaces

SYNOPSIS

       m6pack [-l] [-s speed] [-x n_ptmx] [-v] ttyinterface pty ..

DESCRIPTION

       m6pack  allows  multiple  6PACK  TNCs sharing the same serial port to be used with the Linux AX.25 kernel
       software. The AX.25 softare has no support for multiple TNCs sharing the same serial line. The  different
       ports are addressed by encoding the port number in the control byte of every 6pack frame.  m6pack watches
       a serial port, and routes 6pack frames to/from the pseudo ttys. The other side of  the  pseudo  ttys  are
       then attached with spattach as normal.

       Statistics  about  the  operation  of m6pack may be obtained by sending the SIGUSR1 signal to the running
       program. On reception of such a signal m6pack will print a set of statistics to the system log if logging
       has been enabled.

       Although  mention  is made of using pseudo ttys as the last arguments, these devices may be normal serial
       ports. However m6pack provides no way in which to set their speed, the speed must  therefore  be  set  by
       some other method.

OPTIONS

       -l        Enables system logging, the default is off.

       -s speed  Set the speed of the serial port.

       -v        Display the version.

       -x number This  option is for Unix98 PTYs. It allocates "number" ptys; their names are written to stdout.
                 When -x is used, the pty arguments are optional.
