peter f83677214f This driver supports the Arnet SYNC/570i ISA cards that is based on the ... HD64570 chip. Both the 2 and 4 port cards is supported and auto detected. Line speeds of up to 2Mbps is possible. At this speed about 85% of the bandwidth is usable with 486DX processors. The standard FreeBSD sppp code is used for the link level layer. The default protocol used is PPP. The Cisco HDLC protocol can be used by adding "link2" to the ifconfig line in /etc/sysconfig or where ever ifconfig is run. At the moment only the V.35 and X.21 interfaces is supported. The others may need tweaks to the clock selection code. Submitted by: John Hay <jhay@mikom.csir.co.za>		1995-11-21 02:32:04 +00:00
