- NOS/BPQ Link - NODEDRV4.COM
-
-
- The 'Packet Driver' I wrote to allow NOS to communicate with the switch
- has been modified to use the BPQ Host mode interface. One copy of the
- packet driver is needed for each radio port to be used by NOS, plus one
- for the loopback port if you want NOS to be able to talk to the switch.
- I dont have a lot of experience of using NOS, but I suggest that if you
- are using TCP/IP over NETROM that you use the lookback port, and let the
- switch handle all the radio links. Only if you are using IP in datagram
- or ax.25 virtual circuit mode will you need to give NOS direct access to
- the radio ports.
-
- Please note that you need at least version 4.03 of BPQCODE.EXE
-
- The following is an extract from my system. You will need to tailor
- it to your own requirements.

-
- If using Desqview, NODEDRV4 must be loaded in the same window as NOS -
- if you put it under desqview the system will probably crash. It takes
- three parameters, the software interrupt number used by NOS to communicate
- with it (in the range 60-7f hex), the BPQ Host port to use to talk to the
- switch (1 - 63), and the number of the radio port to be accessed.
-
-
- Please note that NODEDRV4 reads BPQCFG.BIN to find what interrupt to use
- to talk to the switch. BPQCFG.BIN must therefore be in the current directory
- when NODEDRV4 is loaded.

- nodedrv4 0x61 33 1 I am using BPQHost ports 33-35, as I use
- nodedrv4 0x62 34 2 the first 32 for a PacketCluster Node.
- nodedrv4 0x63 35 3 I have given NOS access to 2 radio ports,
- nos and a loopback port to the switch.

-
- This is the 'attach' bit of AUTOEXEC.NET. I can't see where the parameter
- following the interface name is used, but the code suggests it is the
- maximum length of the transmit queue. The next param is the MTU.

- This is a new facility, and there is very little local IP activity for
- me to try it with. Any feedback would be most welcome, both on problems
- and suggestions on how best to set up the system.
