<P>Subject: Re: [TMD700A] "Opening TNC" Fix without reset</P>
<P> </P>
<P>I can confirm that the problem is GPS communication related. I recently </P>
<P>switched from a moded Tripmate to a Motorola Nextel i88 for my gps. The </P>
<P>phone GPS stream can do weird stuff while it is in the cradle while the </P>
<P>D700 is in APRS mode. Once a week it will hang the D700 into the </P>
<P>"Opening TNC" routine. I will have to try resetting the TNC via the </P>
<P>serial port, but in the mean time I'll just reset the PM which doesn't </P>
<P>nearly piss me off as much as doing the hard reset.</P>

<DIV><FONT face=Arial size=2>Occasionally after using the 700 in PKT mode
while connected to UIVIEW, I cannot get back to APRS mode after
disconnecting the application. I can go from PKT to "off", but then
when trying to get back to APRS I get the OPENING TNC message but nothing
else. I have to do a partial memory reset. I should add that
sometimes I have been using PE PRO in KISS mode. </FONT></DIV>
