NAME

6       mkiss - Attach a multi KISS interface

SYNOPSIS

9       mkiss  [-c]  [-f]  [-h]  [-l] [-s speed] [-p pollrate] [-v] [-x n_ptmx]
10       ttyinterface pty ..

DESCRIPTION

13       Mkiss allows dual port TNCs or multiple TNCs sharing  the  same  serial
14       port  to  be used with the Linux AX.25 kernel software. The AX.25 soft‐
15       ware has no support for dual port TNCs or  multiple  TNCs  charing  the
16       same  serial  line.  The  different ports are addressed by encoding the
17       port number in the control byte of every kiss frame.  Mkiss  watches  a
18       serial  port, and routes kiss frames to/from the pseudo ttys. The other
19       side of the pseudo ttys are then attached with kissattach as normal.
20
21       Statistics about the operation of mkiss may be obtained by sending  the
22       SIGUSR1  signal  to  the running program. On reception of such a signal
23       mkiss will print a set of statistics to the system log if  logging  has
24       been enabled.
25
26       Although  mention  is  made of using pseudo ttys as the last arguments,
27       these devices may be normal serial ports. However mkiss provides no way
28       in  which  to  set their speed, the speed must therefore be set by some
29       other method.

OPTIONS

32       -c        This enables a one-byte checksum on each incoming and  outgo‐
33                 ing  KISS  frame on the serial port. This checksum is used by
34                 G8BPQ KISS roms to maintain the integrity of KISS frames.
35
36       -f        This enables a 16-bit checksum on each incoming and  outgoing
37                 KISS  frame  on  the  serial  port.  This checksum is used by
38                 Flexnet Node and BayCom Mailbox to maintain the integrity  of
39                 KISS frames.
40
41       -h        Enables  hardware  handshaking on the serial line to the TNC.
42                 The KISS specification states that no hardware  flow  control
43                 shall  be used so the default is off. But some KISS implemen‐
44                 tations do use hardware flow control.
45
46       -l        Enables system logging, the default is off.
47
48       -s speed  Set the speed of the serial port.
49
50       -p pollrate
51                 Enables polling. Polled mode is used by G8BPQ  KISS  roms  to
52                 prevent  contention  on systems where multiple TNCs share the
53                 same serial line.  Pollrate is  interval  between  polls  (in
54                 100ms units).
55
56       -v        Display the version.
57
58       -x number This  option  is for Unix98 PTYs. It allocates "number" ptys;
59                 their names are written to stdout. When -x is used,  the  pty
60                 arguments are optional.
