The quick fix is going to be to run IP unnumbered on the serial ports:
int s 0
ip unnumbered e 0
In RIP, you *cannot* create a "disjoint", or discontiguous classfull
network by dividing it with a different network. In this case, you're
dividing the class B network 165.243 with a class C network 192.1.1. Rip
can't deal with this. In later versions of the IOS, you can run a protocol
such as OSPF, and "IP classless", and I believe what you're doing would
then work. I've appended an article from the fuzzy search cisco mailing
list (http://www.nexial.nl/cgi-bin) which also addresses this... Also check
out note 1054.
BTW, 9.14(1) is the first version of 9.14- if your customer is
stable, you may want to leave well enough alone, but if not, consider
upgrading to the latest 9.14 (which is still unsupported, as are all
variants of 9.14)- see notes 5 &6 for kit locations.

Unless you're running a routing protocol which sends mask information
around (like OSPF, integrated IS-IS, or EIGRP).
