[TowerTalk] DOS?

[Roger (K8RI) on TT]

Be careful with serial ports. Not many commercial computers have com 
ports. Only recently have new motherboards had serial/com ports as 
opposed to USB)
I'm going to have to look into Python.  I try to stay from anything that 
interprets because of latency compared to compiled. When I graduated, 
none of these new languages existed. Even grad school used C
