Yeah, well, RS-232 is an industry standard, but can I just plug my
industrystandard whatever into the back of my Amiga 1000? No. And apparently
Commodore didn't implement it the way Smith-Corona thought was standard. I just
want to know how Commodore implemented it so I can patch my printer into my
computer. The SCM manual says that pis 4 and 20 go high when the printer can
accept data, low when it can't. What does the Amiga expect to see? Why is this
such a hard question?
Bob,
If you are using a standard modem cable, it will not do. What you need is a
NULL MODEM cable designed to communicate between two pieces of equipment that
both think they are DTEs (Data Terminal Equipment). Pin 4 on the printer should
be connected to pin 5 on the Amiga, and pin 5 on the printer should be
connected to pin 4 on the Amiga.
