One of the remote PCs will be running FreeBSD, and it appears that the cheapest way to accomplish the link using existing equipment is to use asynchronous serial ISDN TA's on both ends. There is a Livingston Portmaster at the central site that has 115kbps serial ports. Using either the Accessworks QuickRemote TA or an Adtran ISU 128 will produce a 115kbps async connection using two "B channels", or so I'm told. So, the question is whether the machine running FreeBSD, assuming it has a serial port with a 16550 UART, can really handle a full 115kbps serial link. I'd use it as a router in this case. Does anyone have first hand experience with any kind of real, sustained, 115kbps serial connections in FreeBSD (or NetBSD or BSDI BDS/OS)? The alternative is an ISDN ethernet bridge or router, but that will cost about twice as much (about $2000 list vs. $1000 list) for the ISDN equipment. Thanks for any comments.
