+.SH NAME
+ao-test-baro \- test AltOS motor testing pressure sensor
+.SH SYNOPSIS
+.B "ao-test-pressure"
+[\-T \fItty-device\fP]
+[\--tty \fItty-device\fP]
+[\-D \fIaltos-device\fP]
+[\--device \fIaltos-device\fP]
+\fIpressure-name...\fP
+.SH DESCRIPTION
+.I ao-test-pressure
+makes sure the pressure sensor input is near mid-band when driven by a 2:1
+resistive divider across the sensor power rail.
+.SH OPTIONS
+.TP
+\-T tty-device | --tty tty-device
+This selects which tty device the debugger uses to communicate with
+the target device.
+.TP
+\-D AltOS-device | --device AltOS-device
+Search for a connected device. This requires an argument of one of the
+following forms:
+.IP
+TeleMega:2
+.br
+TeleMega
+.br
+2
+.IP
+Leaving out the product name will cause the tool to select a suitable
+product, leaving out the serial number will cause the tool to match
+one of the available devices.
+.SH USAGE
+.I ao-test-pressure
+opens the target device and queries the current pressure sensor input data
