+.SH NAME
+sersniff \- a program to tunnel/sniff between 2 serial ports
+.SH SYNOPSIS
+.B sersniff
+.RI [-h] [-i DEVICE ] [-o DEVICE] [-b BAUD] [-s] [-n] [-w USECS]
+.SH DESCRIPTION
+This manual page explains how to use the
+.B sersniff
+command.  
+This manual page was written for the Debian GNU/Linux distribution
+because the original program does not have a manual page.
+.PP
+.\" TeX users may be more comfortable with the \fB<whatever>\fP and
+.\" \fI<whatever>\fP escape sequences to invode bold face and italics,

+.SH OPTIONS
+A summary of options is included below.
+.TP
+.B \-h
+Show summary of options.
+.TP
+.B \-i \fP\fUfile
+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.
+.TP
+.B \-o \fP\fUfile
+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.
+.TP
+.B \-b \fP\fUbaud
+Specify baud rate for serial connections. Defaults to 19200.
+.TP
+.B \-s
+Make sersniff not copy data between the two ports - useful if a
+Y cable is being used for serial port sniffing for example.
+.TP
+.B \-n
+Don't do any port configuration.
+.TP
+.B \-w \fP\fUusecs
+How many microsecs to wait before reporting a delay
+.TP
+.B \-x
+Show hex characters instead of normal ASCII characters.
+.B \-f
+Specify the format string that should be used to print hex characters.
