Re: SNA over TCP/IP

[PaulMmn <PaulMmn@xxxxxxxxxxxxx>]

Although I prefer SNADS to DDM by a wide margin, remember that a 
well-written pair of send/receive programs can give better throughput 
than SNADS.  SNADS has a lot of error-correction and recovery built 
in: "Neither rain nor snow..."  your file -will- get to the other 
end!  But all that protection does come at a price.

Years ago we built ourselves a pair of programs that send a save file 
from machine to machine.  They're simple send/receive programs, but 
have next to no recovery.  Our machines are in the same room, so 
transmission problems are very few.  I suspect that running SNA via 
TCP/IP (with its built in error recovery) would give fairly good 
protection, but you'd have to start any retransmissions by yourself.
