You can do this only in ModemManager git<br> master (not in 1.6.x or before), by specifying a custom udev rule<br> like, see:<br> <a href="https://lists.freedesktop.org/archives/modemmanager-devel/2017-March/004075.html" rel="noreferrer" target="_blank">https://lists.freedesktop.org/<wbr>archives/modemmanager-devel/<wbr>2017-March/004075.html</a><br> <br> For a USB modem, it would be something like:<br> # vim /lib/udev/rules.d/77-mm-<wbr>serial-iridium.rules<br> ACTION!="add|change|move", GOTO="mm_serial_iridium_end"<br> SUBSYSTEM=="tty", ATTRS{idVendor}=="1edd", ENV{ID_MM_TTY_BAUDRATE}="<wbr>19200"<br> LABEL="mm_serial_iridium_end"<br> <br> For a serial modem, try to use the DEVPATH instead (as there's no<br> vid:pid to match), e.g.:<br> # vim /lib/udev/rules.d/77-mm-<wbr>serial-iridium.rules<br> ACTION!="add|change|move", GOTO="mm_serial_iridium_end"<br> DEVPATH=="/devices/pci0000:00/<wbr>0000:00:1d.0/usb1/1-1/1-1.3/*"<wbr>,<br> ENV{ID_MM_TTY_BAUDRATE}="<wbr>19200"<br> LABEL="mm_serial_iridium_end"<br> <br> Once the rule is in place:<br> $ sudo udevadm control --reload<br> $ sudo udevadm trigger<br> <br> And restart ModemManager.<br> <span class="HOEnZb"><font color="#888888"><br> -- <br> Aleksander<br> <a href="https://aleksander.es" rel="noreferrer" target="_blank">https://aleksander.es</a><br> </font></span></blockquote></div><br><br clear="all"><div><br></div>-- <br><div class="gmail_signature" data-smartmail="gmail_signature"><div dir="ltr"><div><div dir="ltr"><div><div dir="ltr"><div><div dir="ltr"><div dir="ltr"><div dir="ltr"><div dir="ltr"><div dir="ltr"><span><font color="#0000ff">Eric Younkin<br>Physical Scientist<br></font></span></div><div dir="ltr"><span><font color="#0000ff">NOAA OCS, </font></span><span style="color:rgb(0,0,255);font-size:12.8px">Hydrographic Systems and Technology Branch</span></div><div dir="ltr"><span><font color="#0000ff">1315 East-West Highway</font></span></div><div dir="ltr"><span><font color="#0000ff">N/CS11, Room 6604<br>Silver Spring, MD 20910</font></span></div><div><span><font color="#0000ff">Office: </font></span><span style="font-family:arial,sans,sans-serif;font-size:13px;white-space:pre-wrap"><font color="#0000ff">240-847-8208</font></span></div><div dir="ltr"><span><font color="#0000ff"> Cell: 828-331-8197</font><br> </span></div></div></div></div></div></div></div></div></div></div></div></div> </div>
