I have a USR 56k internal PnP modem (with no jumpers). It is COM 3 IRQ5. I
am having a hell of a time getting it to work. I have tried everything: all
the HOW-TO's, FAQ's, etc. I used isapnp/pnpdump. got a isapnp.conf file
set up. used setserial. All the config files "seem" set up correctly.
When I try something like :
echo ATH0 > /dev/ttyS2 I get nothing (no error, no response). In minicom I
can dial any number but I don't get anything - no response, no error, no
nothing. Under KDE 's kppp it just says "modem is busy" when I try and run a
test. It is very weird because everything seems to be set up right but the
modem just does nothing....no errors...nothing - it's totally dead. In the
process of trying to configure this modem I have made some improvements as
far as getting things like echo ATH0 > /dev/ttyS2 to work without giving me
an input/output error, and getting minicom to work without giving me an
error message. But now it "totally dead".
I am TOTALLY stuck. I have been reading many posting about this same USR
modem and have 2 questions:
#1 does anyone have any ideas I can try to get this working? Any
troubleshooting tips? Any step by step guides? anything?
#2 am I better off just getting another modem? Has anyone gotten this
particular modem to work with RedHat 5.2?
