Hi, The maximum FDDI packet size is 4495. The spec states that the maximum size is limited by the nature of the clocking. For reasons specific to my application and the 3Max FDDI adapter it would be extremely convinient if the max FDDI packet size were 4096+512=4608 If I change the driver to support the FDDI packet size of 4608, would I break the physical protocol? Or might it still work with the max packet size of 4608? Thanks in advance for any comments. Regards, Lev.

Ask Dirty Harry says, `How lucky do you feel today?' Obviously whether you can do it at all depends on the hardware. If you can do it with the hardware, then the question is, are the clocks on adjacent stations on you LAN closer in speed than is required by the FDDI spec. If not, then the bit rate that the data arrives at one stations will either overflow or underflow the elasticity buffer and the the packet will be damaged. If this does happen at all, then it will tend to happen a lot. It isn't enough to worry about the sending and receiving stations, you must also worry about every station in between. | |||||

If you do that it won't be supported. Do you still want to do it? paul |
