i used the hppa just as 'console' to access an embedded-ppc
i reconnected the same cable to my pc and started minicom there
and it worked
on 9600baud i can use minicom on the hppa as on the pc

i also know there seems to be some kind of 'bug' that on most computers i
have to close and reopen the serial-device to get the baudrate change
in case of minicom it means to set the baudrate, save it as default , then
quit and restart minicom

if setting it manually don't work, how should a automatic work??

there is no terminal protocol, its just that accessing the ootloader on
the ppc happens via 9k6 and 'flashing' it happens with 57600

i'm fairly shure that it MUST be an hppa soft/hardwareproblem since i
switched the cables and they are working correctly on other machines as on
9k6 on the hppa



ps: i will try to find out which is the setting my serial-port is is when
it should be 57600 by just feeding it with different baudrates and watch
when its displayed correctly soon
