Hello,
	I hope there are some O.S. level experts or system developer or software 
porting experts here who could answer or give advice to my question. I am 
involving in a project of porting the TCP/IP layer software onto an 
operating system. The problem is that the O.S. which implement inter-process 
communication by only the support of semaphore and message queueing 
mechanism, but do not support the feature of standard UNIX signal mechanism. 
And that TCP/IP layer software written in C, need the mechanism of the UNIX 
signal in order to work. Does anyone of you know anything related to how to 
simulate/replace/get around the UNIX standard signal mechanism with any 
other ways or could suggest me any other ways to solve the problem? Thanks 
in adavance.

Kin
