If it's an internal (possibly "plug-and-pray") modem which appears as
a third (or subsequent) serial port, it may be connecting itself to
IRQ 7, in which case you'd need to use the setserial(8) utility at
boot-time to tell the kernel that there's a nonstandard serial port,
using a nonstandard IRQ.
I'm a little rusty on Red Hat, but the command
find /etc -name "*serial*"
will locate the file you need to examine, probably
/etc/init.d/setserial or something like that.
