[comp.unix.wizards] UUCP `x' protocol

heath@ncrcae.Columbia.NCR.COM (Robert Heath) (01/04/90)

For what type of network is the UUCP `x' protocol intended ?  
For example, `g' protocol is for TTY lines, `e' is for error-free LANs, and
`f' is for X.25 PAD's.  
I have heard that the UUCP `x' protocol is for use with the 
rather obscure Bell X.25 protocol but I can't seem to substantiate that
in my AT&T documentation.  Anyone got an idea on where `x' is used ?

'x' protocol makes some assumptions that turn out to impractical in the
real X.25 world: first, the network will transparently pass 8-bit data,
and second, a zero-length write() will be propogated end-to-end.  As
Peter Honeyman once said, it's a good thing no one uses it.
