I couldn't find any answers on this thread to the following query:

Is it possible to save the settings for rdesktop 1.7 into a named file so they can be loaded at runtime?

I have 3 PCs that I need to access regularly and its becoming a pain to have to enter the settings by hand whenever I need to change machines. Typically, in a remote support session, I'll need to bounce between 2 out of the 3 PCs several times.
