W8SDZ@WSMR-SIMTEL20.ARMY.MIL (Keith Petersen) (12/18/88)
Now available via standard anonymous FTP from Simtel20: Filename Type Bytes CRC Directory PD1:<MSDOS.ZMODEM> DSZ1216.ARC BINARY 84732 9C84H DSZ is a stand-alone modem program which saves the comm port status, installs its own comm interrupt handlers, sends or receives files using ZMODEM, True YMODEM(Tm), and XMODEM. It restores the old comm port status before exiting. Features include buffered RX/TX for good background performance, "Talk" command for interactive operation and background transfers in <70k DESQview etc. window, table driven CRC-32, Crash Recovery(Tm), and advanced file management. This version, dated 12-16-88, introduces ZMODEM RLE compression with the -Z option. ZMODEM RLE compression packs runs of the same character in two or three character sequences. Compression is useful for screen dumps, uncompressed workspaces, compiler listings, and other files rich with strings of repeated characters, but not .ARC and .ZOO files. Compression percentages range from 0 for already compressed files to more than 1000 per cent (10x speedup!) for the Personal Computing text file benchmark(!). When sending to programs that do not support ZMODEM compression, the -Z option is ignored. The "estimate" command is fixed. DSZ is shareware. It must be registered to gain the use of some advanced features. Beginning with this version a new serial number system has been employed. If you are a registered DSZ user and find that your SNP is not accepted by the program, contact the author for a new number. --Keith Petersen Maintainer of the CP/M & MSDOS archives at wsmr-simtel20.army.mil [26.0.0.74] DDN: w8sdz@wsmr-simtel20.army.mil Uucp: {ames,decwrl,harvard,rutgers,ucbvax,uunet}!wsmr-simtel20.army.mil!w8sdz
