[Macpartners] Sending to RS-232 devices

[David J. Broderick]

I use scripts on the PC to turn various projectors on and off and to switch inputs. I use a separate file which contains the instruction itself because some instructions can be in Hex, and others are simply ASCII. Below is an example of what works on the PC.

I assume there are USB to RS-232 devices for Mac. Has anyone done anything like this on a Mac?

PC Example, where 'NEC-on' is a tiny file containing a string:
\\\\\\\\\\\\\\\\\\\\\\\\\\\\
@echo off

mode com1 38400,N,8,1

copy NEC-on com1

Exit
\\\\\\\\\\\\\\\\\\\\\\\\\\\\
The file above spits the contents of NEC-on to com1 at 38400 baud...
