Here is a link to >one: >http://www.topmicrousa.com/break-1.html I finally found one of mine, only about a foot down in the Midden Heap my pool table has become, and it confirms that the other end is not using any sort of hardware flow control regardless of the options to do that being set in the device descriptor. xon/xoff appear to work, but for some unk reason, the flow rate achieved overall at 19,200 baud, is about 50 baud due to repeats. If you don't disconnect on rzsz, it will get the file moved, eventually, with very very heavy emphasis on the eventually. :( So now I have about 25 pages of assembly code to wander thru, and its comments aren't always that verbose, so those rarely used codes I have to look up in the moto programmers manual. This should be fun, not! Q? This code uses the 'sleep(1)' call to time its repeat scans. It is using no cpu as its the bottom item on an htop sorted by use report. I assume I can go into the tarball and change those 2 sleep calls to sleep(0.05) to get 20 scans a second? I'm going to try it anyway & see if it will still build. Thanks Les. >There are others, but this should help you find what you want. >Regards, >Les H > -- Cheers, Gene "There are four boxes to be used in defense of liberty: soap, ballot, jury, and ammo.
