Virtual H89 Computer HostFileBdos Device

HostFileBdos makes a native directory appear like a CP/M disk via CP/Net. File names are forced to lower case, and files under "user IDs" greater than zero are prefixed with the user number and a colon (":"). Files with names longer than the CP/M 8+3 format produce unpredictable results, but this module is otherwise compatible with the native OS. Note, however, that CP/M always writes in blocks of 128 bytes and will use ^Z (0x1a) as the text file EOF. Also, CP/M text files have both CR and LF for line endings. Viewing text files on the host OS, that were created by CP/M, may show unusual characters, especially following (and including) the terminating ^Z. Linux has utilities for converting line endings. A Linux text file must have CRs added to the line endings, but there is a (new) CP/M-Plus utility TR.COM that may be used to copy text files in or out of CP/M. HostFileBdos is configured as follows:

hostfilebdos##_root_dir

Root directory for server "##" drives (A: through P:). This directory will be created if it does not exist. This may also be specified as the first argument in the cpnetdevice_server## property. Default is "~/HostFileBdos". Drives appear as subdirectories with names "a" through "p". Drive subdirs are created automatically by CP/Net only when set as default drive (e.g. "A> P:(enter)"), but may also be created manually on the host (e.g. 'mkdir').

hostfilebdos##_lst#

Configuration of server "##" list device "#" (hexadecimal). Note, CP/Net LST: output requires use of ENDLIST.COM (or printing an 0xff character) in order to properly terminate a print job. This character will end up in the data sent to the list device. Value syntax is as follows:

>file [a]

Send printer output to file. If "a" is specified, file will be appended instead of overwritten.

|command [args...]

Send printer output to command. Not yet implemented.

ClassName [args...]

Send printer output to an instance of ClassName. The class must implement OutputStream. Currently, only "Diablo630Stream" exists.
