+.TH EDD_ID 8 "November 2005" "" "Linux Administrator's Manual"
+.SH NAME
+modem_caps \- udev callout to identify Hayes-compatible modem capabilities
+.SH SYNOPSIS
+.BI modem_caps
+[\fI--export\fP] \fI<devpath>\fP
+.SH "DESCRIPTION"
+.B modem_caps
+is normally called from a udev rule, to provide udev with the modem
+capabilities for Hayes-compatible modems.
+.SH USAGE
+.B modem_caps
+opens the tty node specified at the commandline and prints the
+discovered modem capabilities.
+.SH OPTIONS
+The following commandline switches are supported to specify what modem_caps
+should print:
+.TP
+.BI --export
+print values as environment keys
+.RE
+.SH SEE ALSO
+.BR udev (7)
+.SH AUTHORS
+Developed by Dan Williams <dcbw@redhat.com>.
