How to get the maximum output from dmesg command

Dear All,

How to get maximum output from dmesg command?
I am unable to see all my debug messages after loading my driver.
I think there is a restriction in displaying the dmesg output.
I saw in printk.c file under source directory. There I found LOG_BUF_LEN
is 16384.
But I am unable to see not more that 300 to 400 lines of code from
dmesg.
If I modify in the printk.c file then I get more lines of code from
dmesg command!!!

As var/log/messages is the source of dmesg command, I made a copy of
var/log/messages assuming that I will be getting the complete driver
trace in it. But a part of the messages that are at the initialization
of our driver are not seen.

How can I get maximum lines of output from the dmesg command?
I am using Red Hat 7.3 with 2.4.18-3 kernel version.
Can anybody help in this regard?

Thanks in advance.
Regards,
Srinivas G
