Limit packet size when talking to Cisco protocol-1 only router

I don't do much with routers any more but at one point I was
configuring a
Cisco via SSH when my session disconnected while pasting large amounts
of text.  I'm told this is common.

I've had this patch for a while but I've not been able to test it. If
anyone is regularly experiencing this kind of issue could you please
tell me if the attached patch helps?

(The buffer size limit is from me, the IGNOREMSG flag is because PuTTY
thinks that particular version has it.)

If anyone can confirm whether or not this fixes the problem please let
me know so we can apply this.
