ZMDM16.ZIP - 138256 bytes ZMDM v 1.6 is another Zmodem program. ZMDM was derived from rz/sz for Unix. It is possible to run at 38.4K or higher baud rates, the changes for this are simple. However, not all ST's run reliably at those rates. The phones module is totally compatible with the earlier program xmdm, so phone directories created with xmdm can be used with ZMDM.
