controlling serial control lines

[Gus]

i figured this was the most relevant list to ask...

i've got a small device (random number generator) which plugs into a
serial port and takes its power off the RTS and DTR lines

i need to raise one and lower the other (and hold them there - this thing
needs some time to 'warm up')

how do i do this?
(all the termios info i've been able to find doesn't seem to say..)
