- _D_s_z uses the YMODEM or ZMODEM error correcting batch
- protocol to transfer files over a serial port with a variety
- of programs. _D_s_z is designed to be called from a
- communications program or bulletin board to perform file
- transfers.
-
- _D_s_z uses its own modem I/O. The original interrupt vector,
- UART interrupt configuration, and 8259 interrupt mask are
- restored on exit. The March 1987 version buffers both
- transmitted and received data, providing enhanced throughput
- with multi taksing systems such as DESQview.
-
- _D_s_z uses DOS standard output for messages, it does not write
- directly to the screen. _D_s_z expects its standard output to
- point to the console, a logging file, or NULL, not the modem
- port. It may be redirected to the console device with the
- CCCCOOOONNNN command.
-
- _D_s_z exits with 0 status for successful transfers, 1 if the
- file transfer failed.
-
- The available commands are:
-
- CCCCOOOONNNN Redirect message output to the DOS "CON" (console)
- device, overriding any previous redirections.
- ppppoooorrrrtttt NNNN
- select port N (n = 1,2,3 or 4) Default is port 1 (COM1)
- or read from the DDDDSSSSZZZZPPPPOOOORRRRTTTT dos environment variable.
- ssssppppeeeeeeeedddd SSSS
- Set specified speed, default is the port's current
- speed.
- dddd Disables carrier dropout monitoring, for modems that do
- not properly drive the "Data Carrier Detect" input on
- the PC.
- LLLLAAAARRRRGGGG Convert AAAARRRRGGGG to lowercase, then parse aaaarrrrgggg....
- ppppxxxxNNNN Set a numeric parameter xxxx to N. These parameters
- correspond to the Pro-YAM or ZCOMM "zmodem" parameters
- and rarely need changing. These parameters assume
- their defaults each time _d_s_z is called.
- rrrreeeessssttttrrrriiiicccctttt
- Restrict pathnames to current disk and directory tree.

- Consult the Professional-YAM or ZCOMM manual chapter
- "Options for File Transfers" for option meanings. The "File
- Transfer Basics" chapter explains the relative merits of the
- XMODEM, YMODEM, and ZMODEM protocols. The "Main Commands"
- chapter describes the rb, rz, sb, and sz commands.

- _D_s_z sets the UART shift register to 8 bits no parity; the
- original parity setting (if different) is not restored on
- exit.
