Thanks for the links! I was working off an old version of Peter Bauman's Serial Programming HOWTO that didn't include the link to the POSIX standard stuff, which ended up being the most helpful. As soon as I get a charged battery (the one in the robot I have at my house is dead and I stupidly forgot to grab a charge), I'll be giving it a try.
