; ----- COM-AND Scripted host mode ----------------------------------
;
; Goals:
; o Must autodetect caller's baud rate
; o Must work correctly for modems reporting true CD and otherwise.
; o Must log all activity
;
; Functions:
; o Passworded log-on
; o DIR of current directory
; o CHDIR command
; o UP and DOWNLOADS
; o Graphical path display (using P/D TREED program)
; o Passworded DOS access (dangerous!)
; o Passworded drop-to-DOS using a doorway function

; Commenced: 10/29/87 R.McG
; Updated: 2/--/89 R.McG
; 10/--/89 R.McG ZMODEM added
; Ver 1.1: 11/--/90 R.McG HOSETUP added
; 6/--/91 R.McG DROPDOS added
; --------------------------------------------------------------
; Data for this script are established through the HOSETUP script.
; The drop-to-DOS requires a doorway function (such as DOORWAY,
; by Marshsall Dudley), and the script HOSTART. The only other
; file requisite to this HOST script is the TREED p/d utility.

  1. Very nice! Thank you for this wonderful archive. I wonder why I found it only now. Long live the BBS file archives!

  2. This is so awesome! 😀 I’d be cool if you could download an entire archive of this at once, though.

  3. But one thing that puzzles me is the “mtswslnkmcjklsdlsbdmMICROSOFT” string. There is an article about it here. It is definitely worth a read: http://www.os2museum.com/wp/mtswslnk/
