4 Port Board Problems??

[Mark Gregson]

	Hi there,
	I am currently running a 4 port serial board that is a
	clone of the AST 4 port serial board. But I am having a
	few problems.

	I was running it under Xenix 286 version 2.2.1 and what
	was happening was I would use the program xcomm to dial
	out from my site. Sometimes when I would start xcomm I
	would try to connect to the modem and would get nothing?
	So in disgust I would exit xcomm and my login would just
	hang, I would then login as the root user and try and kill
	the xcomm process which would never succeed. I could kill
	my user login but never the xcomm process? Then if I tried
	to log back in and try again xcomm would come up with errors.
	No matter what I did I could never be able to kill the bad
	xcomm process. This problem only occurs on one of the ports
	on the 4 port board, never tty1A which is a normal COM port.

	The only way to get out of this problem was to reboot, once
	this was done the xcomm program would work fine and I could
	talk to the modem. I have since changed from Xenix 286 to
	Xenix 386 but the problem is still there?? 
	It seems the port is either locking up or something is holding
	the port open. I realize that this board would not be the best
	quality but a friend of mine has a similar board that works fine.

	Any ideas on the above would be greatly appreciated.

	Regards, Mark Gregson
