- The EIA is probably the modem port. The AUX port would then be the serial
- printer port (but it could mean considerably more -- see below!).

- Does your Atari have an RS232 interface as well? This is where it can get
- interesting (strange, but interesting 8-)).

- There is! Without docs it's going to mean some guesswork (I'm basing this
- on my experience with a VT-220, which had _3_ serial ports of various types)
- and it's pretty much theoretical, but it SHOULD work.
-
- You'll need and RS232 interface on the ATARI, access to whatever configuration
- capabilities the terminal has (if the keyboard has a "setup" key, and it brings
- up the internal menus, you're in luck; otherwise, your chances are very slim),
- and possibly a null modem cable which will go from the ATARI's RS232 port to
- the AUX port (it may not be necessary, a regular modem cable might do).
- Without these, you might as well stop here.
-
- OK, now on to the procedure. Pull up the terminal's setup menu and see if
- is a section/submenu for the auxiliary, secondary serial, or serial printer
- port (the AUX port, in other words). Then see if you can make the port go
- bi-directional (as opposed to output only, if it was connected to a printer).
- Now here is where you will need to find out if you need the null modem/regular
- serial cable. If the section/submenu allows you to configure it as a data
- terminal(DTE) or data communication(DCE) type port, you're in luck; you can
- choose between a null modem or a regular serial cable, respectively.
- Otherwise, you will probably need a null modem cable. After hooking the
- computer up to the AUX port, configure the AUX port to match the Atari's
- parameters (you might even be able to up the baud rate to 9600, but it won't
- do much good, obviously). By then the Atari should be able to talk to the
- terminal AND to the modem.
-
- Note that this is highly dependent on finding what you need. If, for
- instance, the printer port allows data to flow in only one direction, you
- are out of luck.
-
- Once this is set up, there may still be problems -- namely, what to do if the
- terminal decides to intercept data from file transfers (i.e., the terminal
- reacts badly to the usually weird characters going back and forth between the
- "printer" and the modem)? Again, check the section/submenu for an "operating
- mode" (or something similar) for the printer. See if there is a selection
- which will cause the terminal to "monitor" the flow without actually inter-
- preting it.
-
-
- I guess that's just about it. If you have any more questions, feel free to
- ask.
