+.TH EDD_ID 8 "November 2005" "" "Linux Administrator's Manual"
+.SH NAME
+probe-modem \- udev callout to identify Hayes-compatible modem capabilities
+.SH SYNOPSIS
+.BI probe-modem
+[\fI--export\fP] \fI<devpath>\fP
+.SH "DESCRIPTION"
+.B probe-modem
+is normally called from a udev rule, to provide udev with the modem
+capabilities for Hayes-compatible modems.
+.SH USAGE
+.B probe-modem
+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
+.TP
+.BI \-\-verbose
+print debugging information
+.RE
+.SH SEE ALSO
+.BR udev (7)
