[App_rpt-users] Parallel printer port output pins?

Mon Apr 11 09:05:32 UTC 2011

Kyle,
Thanks for the help.  I have it working now.  First thing I did after
receiving your email was ground all of the ground pins.  That may have
helped.
I think it may have been working all along but I made an
incorrect assumption.
I assumed that the "pp2=out1" type lines in usbradio.conf would initialize
the pins to that state as soon as asterisk was started.
It does not.  It just initializes how the pins will be set when the next
"cop 61" is activated or a PTT event happens.
I came up with a fix for this so that the initialization commands actually
initialize the pins on startup.
My fix may not be the right way to do this but it works for me for now.

(Jim, please tell me if this is okay or if there is a better solution.)

Here is a diff showing the fix.
