- The protocol parameters for the UUCP g protocol under ESIX SVR4.0.3
- can sort of be set using /usr/lib/uucp/Config. The "sort of" is
- because you can only set the window size, not the packet size.
- There's a bug in uucico; if you change the packet size to be greater
- than 64 bytes uucico gets all out of sync and that's the end of that.
-
- To increase the g protocol window size, add something like this to
- /usr/lib/uucp/Config:
-
- Protocol=G(7,512)g(7,64)
-
- (This example sets both the G and the g protocol. G protocol is an
- SVR4ism, I believe.)
-
- In /usr/lib/uucp/Systems, add the protocols you want in the 3rd field
- of the appropriate host entries:
-
- somehost Any ACU,Gg etc....
-
- The window should now be 7 on uucp g (or G) connects to "somehost". I
- used truss(1) on uucico to look at the protocol, and it does indeed
- negotiate a window size of 7.
-
- The throughput seems to have increased, as expected, though it's hard
- to be sure -- the "error correction" light keeps flashing on my modem,
- so I think I am getting some bad phone connections.
-
- Too bad the packet size can't be set, that would probably provide a
- more significant performance increase.
