Hi Doug,
I don't know why I didn't do it before, but I just Google'd "RS-232 on
OSX" and got several suggested links. Naturally, I clicked on the one
that was from LowEndMac.com !! :-)
Here's the related passage that caught my eye, under "Serial
Connections:
"Most Macs today don't have legacy serial ports, so you will need to
pick up a USB-to-serial adapter like the IOGear GUC232A. IOGear
provides the drivers for Mac OS X, so all you will need now is a good
terminal app. A terminal emulator is a command line shell that in the
old days was a physical dumb video terminal connected to a big
mainframe. Yes, it's very similar to Mac OS X terminal but it uses the
serial connection for its input and output.
"Terminal Emulation:
"The long-standing king in the Mac world for that past 10-15 years is
Zterm. You start off by selecting your interface (in our case it would
be the USB-to-Serial adapter), set up the basic settings (like the
terminal set to vt100) and connection to Data Rate: 9600, Data Bits: 8
Parity: none, and Stop Bits: 1. I haven't had any problems access
devices using these settings."
So I guess it *IS* somewhat possible. Now all we need is someone to
TRY it! :-)
