[ale] max on SS2 serial ports?

[foobar at stargate.totalchaos.org (Eric Webb)]

I want to set up my SS2 as a firewall/masq gateway, but I'm wondering if
it would be capable on two points:  

  1) How high can the serial ports go?  Are they reliable at this speed?
     How can they be made to go faster (if MAX is around 38.4K)?

  2) Can the box as a whole handle the burdens of routing that an analog 
     dialup would introduce?  Would it be able to handle the volume
     that an ISDN connection would be capable of?


Thanks,
Eric
