- Introduction
- ============
-
- RyDOOR is a utility to allow remote use of your computer via modem.
-
- If you've ever tried running programs remotely by 'dropping to dos' you are
- probably aware of the DOS command CTTY. This is a function that all DOS
- input/output to be redirected to the com port and therefore your modem. The
- limitations are severe however. You may only run programs that do ALL i/o thru
- DOS. This means that all video and keyboard calls have to be exectuted thru
- Interrupt $21. Slow! Slow! Slow! And you'll find many programs that just don't
- do it!
-
- RyDOOR does this one better. It grabs the video ($10) and keyboard interrupt
- ($16) and redirects thru the com port. If the video involves a 'move cursor'
- command RyDOOR automatically translates the command into the ANSI equivilent.
- This means that you must be using a communcations program (remotely) that
- employs an ANSI terminal driver....not too difficult these days...Procomm,
- qmodem and just about any respectable comm program will handle it.
-
- READ THIS!
- RyDOOR also grabs the timer interrupt and periodically checks to make
- sure that carrier detect is high. If not the system will re-boot. This
- means that you don't need to load watchdog or a similar program to check
- for unintentional carrier drops. Because of this feature you must not try
- to run this program locally!
-
- RyDOOR may not work properly with some concurrent operating systems. My
- advice is to get it working in DOS first and then changing over to a
- concurrent system when you have RyDOOR working satisfactorily.
-
- This is the version that can run a program from within it!
-
- usage:
-
- RYDOOR5 [2] [B:xxx] [T:yyy] F:filename.ext [filename parameters]
-
- where items contained in square brackets are optional and without
- the brackets.
-
- The 2 indicates comm port 2 (comm port 1 is default)
-
- The B: option allows you to specify a key that will escape RYDOOR
- and the program in which you are working.
-
- The T: option allows you to specify a key which will reboot the system
- when pressed.
-
- Only valid ascii characters are accepted and control characters are OK.
- The xxx and yyy are the integer equivilent of the key you wish.
-
- NOTE: The F: parameter (along with its' program parameters) MUST be the
- last parameter on the line!!
-
- examples
-
- RYDOOR5 B:3 T:20 F:\command.com
-
- This will run command.com thru RYDOOR. All programs that you load from the
- DOS prompt will use RyDOOR for redirection.
-
- it will abort the program by pressing ^C
- it will re-boot computer by pressing ^T or dropping carrier
-
- RYDOOR5 B:3 T:20 F:ued.com /b
-
- this will run the ued utility via bios calls...
-
- it will abort the program by pressing ^C
- it will re-boot computer by pressing ^T or dropping carrier
