[comp.sys.sgi] input to serial ports

BUG@SWAT.SWARTHMORE.EDU (07/18/89)

Can I have advice from someone on sending integers in ASCII format to
my 4D/70 through one of the RS-232 ports on the back the towers?  We are
building/have built a joystick and would like to send a stream of
triples of numbers:  x  y  z   in a way which can be comprehended by
a graphics routine.  Do we need (horrors!) some fancy driver in order to
accomplish this?  Thanks!
