Here's a couple of .LMP files for DOOM2 that my friend Alex and I
played over the modem. We played Deathmatch on level 2 ("Underhalls")
and level 7 ("Dead Simple"). Of course, since he's better than I am,
he got more frags than I did. ;-)

Gray guy - Dave (me!)

We tried for three hours to get modem play to work right, and all the 
command line switches we had to use to get a modem recording to work
didn't make things easier. These two recordings are two of the rarer 
exceptions. 

How to run these demos:

Pretty simple stuff, actually...
