Hi,
there was great trouble getting UUCP to work with with these new control-
ler-embedded 16550-FIFO-SIOs. It did work as usual until the line "handshake
successful", and then was not able to receive one single block of data with-
out error, until after about 10 Minutes it reports: 0 bytes transferred, 0
bps. This is baudrate-independent, it happens with 300 baud as with 57600
baud. With g-proto, uucico can send, but won't receive anything.
Oerating System is FreeBSD-2.1, and everything else does work on that SIOs
(Xmodem, Zmodem, PPP). UUCP does work with the OS and the configuration,
if one puts an additional, usual SIO add-on-card into the machine (no matter
if 8250 or 16550).
When i got angry about that, i started to change values in the uucp-source.
I succeded in libunix/serial.c by disactivating the "setmin" code (it
says: "if we can tell the terminal not to return after we have a certain
number of characters, do so."). uucico consumes some more CPU power now,
but runs with good performance.
Explanations, anybody?
Peter
