The only necessity is that your serial I/O driver be able to do 115.2Kbaud without overruns. I know that the NetBSD com driver wasn't capable of doing this at one time, but I've also seen substantial improvements to it over the ensuing months and it's quite possible that you can now do 115.2K realisically with NetBSD. Total cost: $319 per TA (new ADTRAN prices) * 2, so the TAs ran me $640 which isn't bad and a fraction of what two Ascend Pipeline 50's would have cost me (about $2200 for both sides). Even if I had had to buy a couple of cheap 386's to do the routing, I still probably would have come out ahead.. :-) Mind you, this is a little bit an of apples-and-oranges comparison since the Ascends will also get you a full 128K syncronous pipe, which is about 39% faster than the 115.2K/async pipe if you factor in the start/stop bit overhead and lower data rate. Still, if you haven't GOT $2.2K to spend then the choice is pretty clear! :-) -- Jordan
