[asterisk-dev] Zaptel drivers Part 2

[Tim Johnson - Eclipse Electronic Systems]

Okay, so after taking Steven Crutchfield's advice and looking into the 
libpri stuff, I decided to mostly use code from pridump.c to start 
experimenting with.  First complaint the code made was in trying to open 
the /dev/zap/1 file while the interface was in signaling 128 mode.  So I 
changed my /etc/zaptel.conf to make all channels dchan, (see below). 

When I do this, operations on the device sort of seem to work as far as 
opening and doing a ZT_GETEVENT.  However when I do a select() on the 
device file, nothing appears to happen.  select() just continues to 
wait, long after data is flowing in.  When I check my syslog, I get 
multiple instances of:

--
Aug 10 09:32:24 timlab kernel: HDLC Receiver overrun on channel 
TE2/0/1/1 (master=TE2/0/1/1)
--


This line comes from zaptel.c. 

Any idea's?  The machine transmitting is using the following format for 
the E1 packet:


HDLC Framing
HDB3 coding
CCS signaling
<more information available if it would help>


Thanks for any help,
