ADTPro Serial Client Configuration

Hitting the "G" key from ADTPro's main menu brings up the serial configuration screen:

You can scroll among the selections with the up and down arrow keys. If your Apple doesn't have up and down arrow keys, the space bar will cycle among the selections.

You can rotate through the options of a particular selection with the right and left arrow keys. Your Apple has right and left arrow keys; trust me.

Note: if you ever end up saving a configuration that is not compatible with the Apple you're trying to run ADTPro on (because you move your serial card to a different slot, for example) you may need to reset ADTPro to factory defaults. To do that, boot the Apple with ProDOS, and get to a BASIC prompt (perhaps using the ADTPro diskette itself). Delete the configuration file from the Applesoft BASIC prompt:

  • DELETE ADTPRO.CONF

That will reset everything to defaults and you should be able to bring up the configuration screen, make corrections, then re-save it.

Comms Device

Super Serial Card (includes IIc, Laser 128 and Franklin Ace 500 modem ports)

Select the slot your communications card is in.

The Apple's slots will be scanned for a serial card or port automatically (until you explicitly save a configuration). The lowest-numbered slot with a card will be selected by default. The IIc+, IIc and compatible computers use the "SSC SLOT 2" setting for their modem ports.

If you have a IIgs and you want to use a Super Serial card in it, ensure you select "Your Card" in the IIgs control panel for the slot your SSC card is in, and select that same slot number here.

Various serial cabling options are discussed in the serial connections section.

IIgs Modem Port

If you want to use the IIgs modem port, rotate through the COMMS DEVICE selections until "IIGS MODEM" shows up:

ADTPro on an IIgs will require a "null modem" cable or adapter when connecting to the host computer. See the IIgs modem port connections section for details.

If you normally start your IIgs with GSOS, you 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 16-bit GSOS has booted, as it modifies the serial environment.

Miscellaneous Serial Devices

Miscellaneous serial devices that do not otherwise have direct support may work with the "GENERIC SLOT 2" setting:

The "GENERIC SLOT 2" selection can be used for any serial device in slot 2 that conforms to the Pascal entry point API. All devices in this scheme are limited to a maximum of 19,200 baud.

Apple /// Serial

An Apple /// machine can use the built-in serial port (marked "RS-232-C") on the back of the machine as well Super Serial cards in any of its four slots. The built-in serial will be selected by default.

ADTPro on an Apple /// will require a "null modem" cable or adapter when connecting to the host computer. See the Apple /// RS-232-C port cabling connections section for details. If you want to use a Super Serial card instead, you will need to select its slot here.

Baud Rate

When in doubt - leave this set to the default of 115200.

115200 is the normal and default baud rate that ADTPro should use. If you have a good serial cable, this speed will work reliably. 19200 is supported for the Apple IIe card in the Mac LC computer. If you can't get 115200 to work reliably, something in your cabling (or potentially your USB driver) is wrong.

Blocks at Once

Blocks at Once tunes the number of 512-byte blocks to send "at once" within a transmission packet. A higher number will make disk transfers go faster, but will offer less immediate feedback as you watch the progress bar move. One block-at-once will make the progress bar run very smoothly; 40 blocks-at-once will be very jerky (but will be the fastest).

Enable Sound

The sound option is, of course, up to you.

ADTPro makes bleating sounds when things finish or abort. I personally think computers should be seen and not heard, but not everyone feels that way. Express your own personal feelings here.

Enable Nibbles

ADTPro can make basic nibble copies of 5-1/4" disks. This might be useful for making a working copy of a very lightly copy-protected disk, or if you are working on de-protecting a disk.

Setting this option to "YES" will present you with the option to send either a normal or nibble image when sending a 5-1/4" disk. This option is not available on the SOS version of ADTPro.

Save Configuration

Hit the "Return" key to work with these parameters. Once you get a configuration that works for you, select "YES" for SAVE CONFIG and hit Return.

This will save a configuration file named ADTPRO.CONF to the same place where you started ADTPro from. When you start ADTPro again, it will use the configuration parameters you saved last.
