No, that shouldn't be.  The D700 start-up file goes to some lengths to 
manipulate the D700 so it doesn't get stuck in the "OPENING TNC" stage, which
is due to a bug in the D700.  It sends commands to disable GPS, then starts
the D700 in "Packet" mode, then turns on GPS.  On shut-down, it turns off
GPS again, switches back to APRS mode (i.e. "display APRS data on the front
panel") and turns the GPS on again.

None of those commands are appropriate for the DR-135.

You can copy the D700 start-up file and comment out all that stuff as a 
DR-135 start-up file, but using the D700 file is not the right approach because
of that extra cruft.

On the other hand, once it does start up and after the small number of 
"Unrecognized Packet" errors, it should behave.  So if you're not getting
to the APRS-IS, then the problem may be that you are not getting gated 
after those few bad packets.  You'd have to check all your raw packets on
aprs.fi or findu.com to see what's actually making it to the APRS-IS.
