Are there any plans to increase the bus bandwidth of USB in the future to 2x, 3x?

No, USB was designed for a desktop peripheral interface and has a performance/cost point for today's peripherals. A new interface, such as P1394, for future high speed peripherals may develop.

Are there any plans to support ATAPI/IDE tape drives on Novell Products?

Not at this time.

Are there USB products out right now?

Yes. Almost all new PC designs from major vendors shipping today have USB connections on the motherboard and the correct Win OS to make them work. There are also many products used to design and build USB systems, such as connectors, chipsets and board-level computers.

Assume IP route cache is enabled on two interfaces not sharing the same MCI card. How is routing between these done? Does the main processor get involved?

This is the same as previous case, except that a bcopy is necessary to move the packet between cards.

Assume IP route cache is enabled on two interfaces sharing the same MCI card. How is routing between these done? Does the main processor get involved? If so, how does it see the packet header to make a routing decision?

MCI interrupts the CPU. The CPU looks at the packet on MCI to get destination, and calculates the route. The CPU rewrites packet encapsulation, and queues the packet on the outbound interface by moving a pointer on the MCI.

Assume IP route is disabled on two interfaces. How is routing between these done?

Packet is read into the CPU. Increment input queue. Route packet. Place on output queue; increment output queue. When packet is placed on outbound interface, decrement output queue and input queue.

At times printer starts printing from first page to second page.

Hold down "F" key & switch on DIP switch setting will print,checkpage length & set page length by DIP switch.

At times,while connecting,I get dropped?

Do you have call waitng?Have you been idle(not loading a page or sending an email or making an file transfer) through the server for more than just a few minutes?Is there any disturbance on the phone line?Did you have a program experience an illegal operation while connected?Are you using a 56K modem that is in conflict with the modem of your provider(X2 versus Kflex tecnology)?

Can a drive be modified for A/V applications?

Current generation Seagate SCSI drives have an embedded servo, so there is no thermal recalibration to interrupt the data flow. The high internal transfer rates, along with the default settings on data prefetch may make the drives sufficient for many A/V applications with no further "tuning". If desired, the performance can be further enhanced by: 1.Increasing the cache buffer segment size, which will maximize the data prefetch feature of the drive 2.Turning off error logging (S.M.A.R.T.) 3.Turning off or limiting retries in case of data errors

Can an interface have more than one "ip access-group" in its configuration?

No, you cannot have more then one access-group per interface. However, if you have 10.0 or higher software then you can have: int ethernet 0 ip access-group 1 in ip access-group 2 out You are using one access-group for inbound traffic and one for outbound traffic.
