PackeTwin, WA4DSY Grapes 56k modem
RedHat 6.1 Linux
HOWTO
I would like to acknowledge those who have helped me with this project. Thanks to Mr. Klaus Kedula, Mr. Dale Hetherington, Mr. Douglas Drye, Paul Williamson and Mr. Brian Kantor for taking the time to help me with this project. This paper does not discuss AX25-Utils installation, which is used to attach the ports to both LinFBB(xFBB) and Jnos/Tnos applications.
Configuring the PackeTwin card was fairly simple. At first I tried to configure Port B as the 56k and make use of the onboard connector. Even though the manual stated that 56k DMA mode would work on either port, I was not successful. After several attempts I moved the 56k serial sync chipset to Port A and set that for DMA mode. Originally I am used IRQ 2 and DMA 3 for card access on a Pentium 133, which worked, but had problems with the DMA mode on a 400MHz Pentium. Now both machines are in the interrupt mode. The DMA problem was garbled output data (even though the trace screen in Jnos looked good). To fix this I disabled the DMA mode by setting the dmascc_cfg dmascc0 -- DMA 0 in the config file (discussed late on). You can pickup the serial sync chips from a electronic supply a lot cheaper than Pacomm. I found them for about $1.00 each.
Once the PackeTwin card is in place, I ran make menuconfig on the /usr/src/linux directory to compile in the High Speed DMA SCC driver for AX.25. Don’t forget to enable Serial port KISS driver as well (usually done when installing AX25-Utils). My baseline is the 2.2.13 kernel. For the most part I use monolithic kernels but have used modules at times. Rebuild the kernel with make clean, make dep and make bzImage. Copy the new kernel to /boot directory and add the new image to /etc/lilo.conf. Don’t forget to run “lilo” after the changes before rebooting.
Ok, now when you boot the kernel should see the dmascc0 and dmascc1 interfaces. Now we need to add the dmascc_cfg configuration tool found at: http://www.nt.tuwien.ac.at/~kkudielk/Linux/
Use “tar xvfz dmascc_cfg-0.7.tar.gz” to uncompress the tool and run “make” in the resultant directory. This will produce a dmascc_cfg binary which I copied to the /usr/sbin directory. I placed the configuration script in the /etc/rc.local file at the bottom of the original script. There I made changes to the txdelay (currently set at 150) and DMA mode (currently set too 0 for interrupt mode only). You may have to do some adjustments to suite your area.
/usr/sbin/dmascc_cfg dmascc0 --speed 0 --nrzi 0 --clocks 0x08 \
--txdelay 10 --txtime 3 --sqdelay 1 --slottime 10 \
--waittime 100 --persist 32 --dma 0
Now when you boot up, your card is configured and ready too go. I make use of the kissattach command set to bring the interface to the axports file. Along with the dmascc_cfg I make use of the ifconfig to set IP address, netmask and broadcast address of each interface. I also load things like rc.ipchains, rc.xFBB, and rc.portsentry in the rc.local file. The dmascc0 and dmascc1 interfaces are shared by both LinFBB (xFBB) and Jnos/Tnos. I found it better to enter the LinFBB bbs application by connecting first to the AX25 Node (node-3.0) first and then using the “bbs” command (defined in the /etc/ax25/node.conf) to reach the application. If I try to connect directly the 256 paclen limitation of FBB creates fragmentation on the MTU level. I also noticed that using the telnet to either the Jnos/Tnos application went smooth as well.
