Start the ADTPro server from your host computer's command line or by clicking on the startup program for your host operating system:
Once started, the server program's GUI comes up:
From here, you can select the communications device you want to use at the host end by clicking one of the shiny buttons (besides Disconnect, of course). If you would like to start the server up already listening in particular mode, you can supply the startup script with the name of the communications mode of choice (as shown on the button). In English, those are Serial, Ethernet, and Audio. For example, the invocation 'adtpro ethernet' starts up the server with the Ethernet button "pushed."
Note that serial communications has an additional set of configuration options, accessible from the File->Serial Configuration menu item. The first time you use serial communications, the Serial Configuration dialog box will come up automatically to allow you to pick a communications port and speed:
When you boot your Apple ][ from the ADTPro disk, it will start a simple menu where you can pick which version of ADTPro you wish to start:
You can navigate among the choices by pressing the first letter of the program, or by using arrow keys and hitting the Return key to select one. Be sure to choose a client program at the Apple II end to match the communications device being used at the host end.
You can have a particular version always start automatically by making it the first (or only) program that ends in .SYSTEM on the disk. Each communications version of ADTPro has two parts: a ProDOS loader, and a corresponding binary program. So, the three versions are named like this:
In order to make one of them start by default (i.e. without having to pick one every time the disk is booted), rename the pair of files (the ProDOS loader and accompanying binary program) to have the same name, except the loader needs to have a .SYSTEM suffix and the binary program needs to have the .BIN suffix. What you rename them to is up to you - but ProDOS limits names to 15 characters. You can't rename ADTPROETH to ADTPROETH.SYSTEM, for example... you need to pick something a little shorter.
These are the specific steps:
So, for example - to always automatically start the audio version, you would:
Once it starts, the main screen comes up:
The best way to test communications is to hit the "D" key from the client to ask for a directory listing at the host. If the client "hangs" waiting for a response from the host, or if garbled data comes back, it will be necessary to check the physical connections, port names and speeds on both host and client ends. The ethernet version of ADTPro (ADTPROETH) often needs a couple of directory queries to find the server after setting up its configuration. If you're using the audio version of ADTPro (ADTPROAUD), ensure the volume setting for your sound card is set to halfway up the scale (i.e. much louder than you'd generally listen to computer speakers).
IIgs/GSOS Note: users running GSOS are advised to hit the '8' key while booting. That has the effect of starting the IIgs in 8-bit ProDOS (BASIC) mode. ADTPro can't maintain the tight timing necessary for serial communications when the full GSOS has booted, as it modifies the serial environment.
Booting a diskette in an Apple /// computer will automatically run any program named SOS.INTERP. The ADTPro distribution diskette comes configured with the serial ADTPro client version named SOS.INTERP. The ethernet version is also on the diskette, but is named SOS.INTERPETH. In order to run the ethernet version, it will be necessary to rename SOS.INTERPETH to SOS.INTERP (also deleting or renaming the original serial SOS.INTERP program). The Apple /// utilities disk or any Apple disk image manipulation utility program like CiderPress or AppleCommander can be used to do this.
