I need to write math using word. I need to write integrals and differential equations and the normal math stuff. But I do not know how to find the symbol set in word. Does anyone know how to get into the format for writing the equations? ---------- > From: Mike Keitz > To: PICLIST@MITVMA.MIT.EDU > Subject: Re: [OT] windows terminal- output? > Date: Sunday, May 03, 1998 7:40 PM > > On Sun, 3 May 1998 17:46:45 -0400 Bill Kennedy > writes: > >Piclist, > > Anyone know what windows 3.1 terminal program actually sends out > >the > >serial port? > > Unless it is very strangely configured, it sends ASCII characters.
