Munging around in both BSD and SysV "cico.c" code, I found a slight 
inconsistency:

		alarm(MAXMSGTIME);
		omsg('O', "OOOOO", Ofn);
		DEBUG(4, "send OO %d,", ret);
		if (!setjmp(Sjbuf)) {
			for (;;) {
				/* the following line is NOT in System V */
				omsg('O', "OOOOO", Ofn);
				ret = imsg(msg, Ifn);
				if (ret != 0)
					break;
				if (msg[0] == 'O')
					break;
			}
		}

From the -x9 logs it looked very much like the BSD uucico was waiting
for another 'O' message (a second one).  I put it in the System V 
version, downloaded it to one of our System V remotes, and it worked 
just fine.  By the way, regarding the suggested "strip parity" fix
mentioned earlier, I have found that our BSD cico strips parity in imsg 
but the System V doesn't.  I will have to investigate that too.

Any comments from uucp experts?  Which is right - strip parity on
both ends, updating System V omsg('O'...) to match BSD, or both?
