OPTIONS¶

A summary of options is included below.

-h

Show summary of options.

-i file

Set the device to use for Port1. Default of /dev/ttyS0. If you want to listen on a TCP port then use the format :port. If there's a / in the string then it will always be treated as a device rather than a port to listen on.

-o file

Set the device to use for Port2. Default of /dev/ttyS1. If you want to connect to a TCP port then use the format host:port. Again if there's a / in the string then it will always be treated as a device.

-b baud

Specify baud rate for serial connections. Defaults to 19200.

-s

Make sersniff not copy data between the two ports - useful if a Y cable is being used for serial port sniffing for example.

-n

Don't do any port configuration.

-w usecs

How many microsecs to wait before reporting a delay

-x

Show hex characters instead of normal ASCII characters.

-z

Don't quit when an EOF character is received.

-f

Specify the format string that should be used to print hex characters.
