Hmmm, that triggers old memories, as it might be a 10 meter usb2 cable with
booster hubs in both ends, which formerly connected the minicom program to a
trs-80 color computer 3 in the basement via an rs232 card plugged into its
multipack interface expander. But it wasn't very fast, the uart chip in it
was all tapped out at 9600 baud, and rzsz was limited to about 7200 baud due
to its loop size being one byte, I was always going to rewrite it to fully
use the table lookup version of the crc calcs but never found a round tuit.
it was highly dependent on flow control working, something that early uart
chip did not do well. Prolific who made the rs232<>usb convertor on the end
of that cable, never did quite get that right.
But that 2 megs of ram "coco" has now died, 35 yo electroytics developing
high ESR so its dead now, and despite my being a CET, I'm too lazy in my
dotage to shotgun all the caps it it, but I believe that cable is still
plugged in to one of several multiport usb 2 or 3 hubs on this machine.
Do we still have a working usbtree like utility that might discover this?
Such useful stuff seems to be falling off the edge in later versions of
linux.
Thanks David.
Cheers, Gene Heskett.
