Recently, our computer users began to complain about type ahead problems on our Vax 8600 (running Unix V 2.2). The problem is that when the CPU gets bogged down, it is possible to be as much as 10-15 characters ahead of what is showing on a terminal. Naturally there are complaints about this. To me, the problem seems obvious -- the cpu is loaded and is taking longer to echo terminal input back. We are currently using VMZ/32N asynchronous communications boards from Able Computer, that allow DMA. I am currently looking about for a board that will replace the VMZ's we have, and in the process, pick up the additional task of performing terminal echo to take this load off the cpu. The boards we have are each 16 line async., and are designed to replace digital's DMF32 boards. Anyone have any suggestions or input as to my quest? If so, please email me. Thanks in advance for any help! ------------- Calvin Hayden (615)461-2254 UUCP: mcnc!rti!tijc02!root ------------- "...and what do you burn under witches? More witches!" The Holy Grail
