I've had two different machines connected to ditka at 19200 for uucp transfers, running HDB. One is formtek, a Sun-3/180 at my office, talking via Telebit TrailBlazers running at 19200 on both sides. Large news batches regularly show 1300-1400 bytes/second as reported in xferstats. (I also talk to a few out-of-state TrailBlazers; these times aren't quite as good but are still in respectable range.) The other case was a hardwire to royko, a 0.5 MB 7300, also with HDB. Here, I only saw about 800-900 bytes/second. Looks like the serial port can handle the speed, but the machine can't really keep up with it. -- Karl Swartz |UUCP {emoryu1,pacbell,decvax!formtek}!ditka!kls 1-412/937-4930 office | {pitt,psuvax1}!idis!formtek!ditka!kls |BIX kswartz "I never let my schooling get in the way of my education."
