The "Host Requirements RFC" (RFC 1122) states that a TCP implementation should implement delayed ACKs, so I bet Cisco does. However, you do realize that it's not very relevant, don't you? How often is the Cisco router the end-point in a TCP conversation? Only when you Telnet or HTTP to it. When the router is just forwarding packets that happen to carry TCP, it wouldn't get involved in ACKs at all.
With Telnet, I bet it's especially not relevant, because the PSH bit gets set which probably resets the ACK timer and forces a (non-delayed) ACK.
