This is a Communications Serial Tool (Extension) which can give comms enabled applications such as ClarisWorks, access to the ZMODEM file transfer protocol.

Imaged as (Disk Copy 4.2) disk image file and compressed as a .sit archive using Stuffit 3.6 for pretty good backwards compatibility.

MD5sum: ec7eb41fd0d0902361bb16febdd155a2 *zmodem-tool-1.sit

To enable, drag the ZMODEM Tool's icon over onto the closed icon of the System Folder and release the mouse. This should bring up a Finder dialog informing you that this item needs to be placed into the Extensions Folder (or similar message). Click OK.

You must restart your Macintosh to enable the Extension.

Once rebooted, you can (for example) start up a ClarisWorks Communications session (See screenshots) and the ZMODEM file transfer protocol will now be available to ClarisWorks.

68k code, runs fine on PPC Macs up to Mac OS 9.2.2
