David Schmidt has updated ADT for DOS to include many of the newer features of ADTPro. According to David’s comp.sys.apple2 post, the following enhancements have been made:

* Compatibility with both the SSC and IIgs at 115.2kbps
* Ability to save itself (no Applesoft configurator)
* NAK protocol error discovered and fixed by Joe Oswald
* ADTCK ADT checksummer program generalized so it’s not version-dependent

These are upgrades to the client only; the servers for MS-DOS and Windows haven’t been changed and are still v1.23.
