Here is an interesting bit of modemania!
My friend and I uucp with our 3b1's. He uses the 3.5 and I use
3.51m. He has a multitech modem with v42bis fixed link rate at
9600. I have a T2500 at 19200 :-). He discovered how to switch
from UUCP G protocol to E protocol. Boy what a difference in
thoughput!
His throughput jumped from an approx avg. 200-226 to 317-960cps.
My throughput jumped also the same.
Not bad with a connect rate of only 2400 baud. The compression
was really working. Even with compressed files it really works
better.
G protocol looks like x-modem on the RD & SD modem LED's.
E protocol looks like z-modem where the SD working at the TX'ing
modem and RD working on the RX'ing modem.
To enter the change to the protocol you must add ',eg' to the
end of the Devices prefix:
EX:
ACUM24,eg tty000
Thats it! However you must be using a error detection modem or
you will have problems.
Does anyone know why this works and what would happen if you
change the ',eg' to ',ee' or ',ge'???
