ENGINEERING RELEASE NOTES


	       CHASE RESEARCH EXTENSIONS FOR LINUX SERIAL DRIVER


				   V2.02


				04 Nov 1999




	CARDS SUPPORTED

	The driver has been rewritten to support the following 
	Chase Research products only.

		 4-port AT-Fast
		 8-port AT-Fast
		16-port AT-Fast (restricted modem control)
		 4-port PCI-Fast
		 8-port PCI-Fast
		16-port PCI-Fast (restricted modem control)
		16-port PCI-Fast (full modem control)
		 4-port PCI-RAS
		 8-port PCI-RAS




	ENHANCED FEATURES

	The range of baudrates has been extended to 460800 bits/sec.

	The on-chip hardware and software flow control capabilities
	of the 16C654 UART are utilised to reduce host load.




	KNOWN BUGS AND DEFICIENCIES

	1. The driver cannot be installed as a module on multi-processor
	systems. It can only be installed as a statically-linked driver.
	On uni-processor systems it can be installed statically-linked
	or as a module.

	2. Data can be lost if multiple ports are run simultaneously
	at 230400 or 460800 bits/sec.
