So I think you'd want to following this pin out diagram:<br> <br> <a class="moz-txt-link-freetext" href="http://docwiki.gumstix.org/Gumstix_motherboard_I/O#Serial_cable_connections">http://docwiki.gumstix.org/Gumstix_motherboard_I/O#Serial_cable_connections</a><br> <br> The pins you described are straight through connections.<br> <br> see the part on serial port connections. Also I'd make sure that you have handshaking tunred off on your PC hyperterminal.<br> <br> 'mark<br> <br> Jarl Magnar Jakobsen wrote:<br> <blockquote type="cite" cite="mid...@ph...l"> <meta http-equiv="Content-Type" content="text/html; "> <meta content="MSHTML 6.00.6000.16525" name="GENERATOR"> <style></style> <div><font face="Arial" size="2">Hi</font></div> <div><font face="Arial" size="2">I have been trying to conect my new gumstix Verdex XM4-bt using the breakout board and a USB->serial dongle.

And are using the correct pinns on the rs232 (2 TXD,3 RXD and 5 GND, also tried the RTS,CTS on the BTUART) The wiki also mensions somthing about a reset button, but dos the Verdex bords have this?</font></div> <div><font face="Arial" size="2">Hope sombody can help.</font></div> <div> </div> <div><font face="Arial" size="2">Best Regards</font></div> <div><font face="Arial" size="2">Jarl Jakobsen</font></div> <div> </div> <pre wrap=""> <hr width="90%" size="4"> ------------------------------------------------------------------------- This SF.net email is sponsored by: Splunk Inc.
