:HELP You may use the HELP command to obtain either a listing of available commands or to get a brief summary of a command. To get a listing of commands, type "HELP" by itself. To get help on a specific command, type "HELP (command name)". For example, "HELP DIR" would get you help on the DIR COMMAND. :ATTRIB The ATTRIB command may be used to view or change the attributes a file or series of files. The syntax is as follows: ATTRIB [+-r +-h +-s +-a] FileSpec (R=Read only, H=Hidden, S=System, A=Archive) :CD The CD (or CHDIR) command is used to change the current directory. For example, typing "CHDIR \DOWNLOADS" would switch you to the \DOWNLOADS directory (providing you have one). You can also type "CHDIR" by itself to get the name of the current directory. :CHDIR The CD (or CHDIR) command is used to change the current directory. For example, typing "CHDIR \DOWNLOADS" would switch you to the \DOWNLOADS directory (providing you have one). You can also type "CHDIR" by itself to get the name of the current directory. :CLS CLS will clear the SDOS window. :COPY COPY is a powerful command that lets you copy files from one location to another. There are two forms of copy supported by SDOS: COPY - Copy a single file COPY CON - Copy keyboard output to file If you use the "COPY CON" format, all keyboard output will be sent to the file until you send a CTRL-Z character. :D: "d:" designates a drive letter. For example, typing "A:" would switch you to drive a, typing "B:" would switch you to drive b, etc. :DEL The DEL (or ERASE) command allows you to delete a file or series of files. DEL accepts one parameter which is the filespec (wild card allowed) of the file(s) you wish to delete. You will be prompted before the erasure is made to make sure you wish to delete the files. :DELNUL DELNUL is a special command that will delete zero-length files. It accepts the same parameters as DEL, but will only files that have a size of 0 bytes. Occasionally, some programs (such as file transfer protocols) may leave zero length files laying around. This command gets rid of them. :DIR The DIR command will list the files in a certain directory. Typed by itself {i.e. "DIR"), the DIR command will list the files in the current directory. You may also specify a directory name (i.e. "DIR C:\TURBO") or a file mask (i.e. "DIR *.PAS") or both (i.e. "DIR C:\TURBO\*.PAS"). Specifying the /P option will cuase the directory to pause after each screen and specifying the /W option will display a wide directory. The "/T" option may be used to display the TRANSFER TIME of each file. :ERASE The DEL (or ERASE) command allows you to delete a file or series of files. DEL accepts one parameter which is the filespec (wild card allowed) of the file(s) you wish to delete. You will be prompted before the erasure is made to make sure you wish to delete the files. :FREE The FREE command will display the free space on a drive. Typed by itself, FREE will display the amount of space on the current drive. By specifying a drive letter, FREE will display the amount of free space on that drive. :MD The MKDIR (or MD) command will allow you to create a subdirectory. The subdirectory created will be a subdirectory of your current working directoriy unless you specify otherwise. MKDIR accepts one parameter which is the directory name/path. :MKDIR The MKDIR (or MD) command will allow you to create a subdirectory. The subdirectory created will be a subdirectory of your current working directoriy unless you specify otherwise. MKDIR accepts one parameter which is the directory name/path. :REN The REN (or RENAME) command will let you rename and/or move files. Unlike dos, you can rename across subdirectory - in effect, moving the file. REN takes two parameters, a source and a destination file name. :RENAME The REN (or RENAME) command will let you rename and/or move files. Unlike dos, you can rename across subdirectory - in effect, moving the file. REN takes two parameters, a source and a destination file name. :RMDIR The RMDIR (or RD) command will let you remove a sub-directory. To do this, there may be no files or subdirectories located within the subdirectory you wish to remove. RMDIR takes one parameter, the name/path of the subdirectory. :RD The RMDIR (or RD) command will let you remove a sub-directory. To do this, there may be no files or subdirectories located within the subdirectory you wish to remove. RMDIR takes one parameter, the name/path of the subdirectory. :SIZE The SIZE command will display a tally of the number of files, bytes contained in the files, and the space that would be consumed on a floppy drive and a hard drive (2048 byte cluster assumed). :TYPE The TYPE command allows you to display a file in the SDOS window. The file may be ascii or binary and will be displayed one page at a time. You will be promped between pages to continue or stop. The TYPE command accepts one numeric parameter which is the filename to display. :ZIPVIEW This command will display the file directory of a zip file. The syntax is ZIPVIEW followed by the name of the zip file you wish to view. (i.e. ZIPVIEW THISZIP.ZIP". :DEBUG DEBUG is a watered-down version of the MSDOS program. With debug, you may view a binary/ascii file in hexadecimal format. Unlike the MSDOS debug, you may not make changes to the file. Typing "H" at the debug prompt will get you a quick command summary. :PORTSPEED This sets the default com port and baud rate that SZMODEM will use. As with all options in this configuration program, these are only defaults and may be overridden with the following command lines options: PORT x - Sets com port SPEED x - Sets baud rate :FOSSIL Some BBS programs use a FOSSIL driver in an attempt to standardize their async communications. Toggling this option to ON will cause this SZModem use the FOSSIL driver instead of SZModem's internal com routines. :DORINFO If your bbs produces a DORINFOx.DEF file when a user logs on, you may use this option to allow SZModem to grab the user's name and city and display it on the screen during transfers. (See SZMODEM.DOC for more info) :INSIZE This will set the input buffer size. The input buffer stores characters after they are read in from the modem until SZModem can process them. Note: Since the FOSSIL drivers have fixed buffer sizes, this option only works with the INTERNAL com routines. :OUTSIZE This will set the output buffer size. The output buffer buffers characters that SZMODEM sends out the com port. NOTE: Since the FOSSIL drivers have fixed buffer sizes, this option only works with the INTERNAL com routines. :SZPATH The SZPATH option allows you to specify a path that the SZXFER$$.LST, SZMODEM.LOG, and other misc. SZModem files will be placed in. :DELAYTIME By default, SZModem will pause a few seconds after a transfer is completed to allow the user/sysop to view the file lists, chat, etc. This option sets how long SZModem will delay. :SZTURBO The SZTURBO option enables a special mode of SZModem designed to increase transfer efficiency. Please see SZMODEM.DOC for more information. :CHECKSNOW This option will enabled snow checking on monitors that require it. Snow checking does slow down screen display, so only toggle this on if necessary. :EGAVGA This option will enable the 43/50 line enhanced screen modes if you have an EGA or VGA display. :NOLOG By default, SZModem will create a special log file for use by the sysop. This option will turn the log file on/off. :NOPAGE Remote users normally are allowed to page the sysop during chat mode. This option can be used to disable that paging capability. :DORINFOPATH This option will set the path to your DORINFOx.DEF file if you use one. If your bbs software does not generate a DORINFOx.DEF, then you probably do not need this option. (See SZMODEM.DOC for more info)
