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

Hello Chuck,<br>
<br>
<br>
I have had great luck with the parallel port under app_rpt.<br>
<br>
First thing to try is: (Make sure Asterisk is controlling the parallel port!)<br>
<br>
# lsof /dev/parport0<br>
COMMAND PID USER FD TYPE DEVICE SIZE NODE NAME<br>
asterisk 25664 root 24u CHR 99,0 1010 /dev/parport0<br>
<br>
Next, make sure parallel port pins 18-25 are grounded. Some ports are quite picky about this.<br>
<br>
Here is my usbradio.conf template for using an IRLP/PLRI board:<br>
<br>
[usb1234]<br>
rxchannel=usb1234<br>
;<br>
pp3 = ptt ; Parallel port settings<br>
pp11 = cor<br>
pp4=out0 ; in, cor or ctcss<br>
pp5=out0 ; multiple pins can be set to PTT if desired<br>
pp6=out0 ; pins 4,5,6 are AUX 1,2,3, default off<br>
;<br>
hdwtype=0<br>
rxboost=1<br>
txboost=0<br>
rxctcssrelax=1<br>
txctcssdefault=100.0<br>
rxctcssfreqs=100.0<br>
txctcssfreqs=100.0<br>
carrierfrom=ppinvert<br>
ctcssfrom=no<br>
rxdemod=speaker<br>
txprelim=no<br>
txlimonly=no<br>
txtoctype=no<br>
txmixa=voice<br>
txmixb=no<br>
invertptt=0<br>
duplex=0<div class="im"><br>
rxondelay=0<br>
rxnoisefiltype=0<br>
eeprom=0<br>
<br>
<br></div>
Next, here's a little script to control parallel pins from a prompt:<br>
<br>
#!/bin/bash<br>
# Script to control PLRI Aux ports from prompt<br>
# by Kyle Yoksh January 2011<br>
#<br>
# Usage: pport [node no] [parallel port pin] [logic state]<br>
#<br>
# Example, pport 2211 2 1 turns pp pin 2 on<br>
#<br>
asterisk -r -x "rpt cmd $1 cop 61,PP$2"="$3 0"<br>
One last thought, I've noticed that app_rpt will not reliably control the parallel port if you have a node configured in rpt.conf for "rxchannel=Radio/usbxxxx" without a fob present.<br>
<br>
73 for now. Good luck.<br>
<br>

I am trying to use the parallel printer port output pins on an Intel ATOM<br>
D510MO mother board. I have included below my usbradio.conf file.<br>
For testing there is a board with LED's attached to the port and on POST it<br>
displays various patterns then nothing until fully booted when it shows only<br>
pin 4 active.<br>
I have tried this with the pport commented out and with the pbase commented<br>
out and the same result. I have tried each of the options available in the<br>
BIOS setup for the parallel port and same result.<br>
The only lines found in the log files that seem to relate to the parport are<br>
the following...<br>
<br>
Apr 10 13:26:10 server8 kernel: parport: PnPBIOS parport detected.<br>
Apr 10 13:26:10 server8 kernel: parport0: PC-style at 0x378, irq 7 [PCSPP]<br>
Apr 10 13:26:10 server8 kernel: lp0: using parport0 (interrupt-driven).<br>
Apr 10 13:26:12 server8 asterisk[2548]: VERBOSE[2548]: -- Parallel port<br>
is /dev/parport0<br>
<br>
<br>
Does anyone have any suggestions as to how I can troubleshoot this or what<br>
might be the problem?<br>
