SSC Serial port control

Hello all,

I once saw a procedure to setup the Apple II to respond to DOS commands though the serial port.

For example, i have my Linux computer hooked up to my Apple II via a serial cable, I want to load/enter/save basic programs

on the Apple II, and have the respones come to my terminal on Linux over a serial cable.

I have done it with my CP/M card and SSC and it works great but I am not sure how to do it from plain Apple DOS 3.3

Thanks

I believe you just need to

I believe you just need to type IN#2 at a command prompt (assuming your serial card is in slot 2). Then press Ctrl-A and enter 15b (sets the port to 19200 baud, 8N1).

Yeah - that's what I'd try.  That is the basic principle as to how ADTPro sends data to the Apple II through the serial port.

(if you prefer a lower baud rate than 19200 - which may improve reliability, type 14B <return> to set the SSC to 9600 baud)

The instructions for this are in the Apple Super Serial Card manual on page 15: https://mirrors.apple2.org.za/Apple%20II%20Documentation%20Project/Interface%20Cards/Serial/Apple%20II%20Super%20Serial%20Card/Manuals/Apple%20II%20Super%20Serial%20Card%20-%20Installation%20and%20Operating%20Manual%201981.pdf

Hi There,If from the DOS

Hi There,

If from the DOS prompt i enter:

 

IN #2

PR #2

 

It does what i need, from the serial port i can hook up my dumb terminal and enter DOS commands or start typing BASIC programs and save them to disk.

 

To Push it, I then created a BASIC program

10 IN #2

20 PR #2

30 exit

 

then: INITIALIZE HELLO

Then i booted with this disk, it booted and ran the BASIC program, but from my dumb terninal i can only enter BASIC commands, if i enter DOS commnads (i.e. CATALOG) , I get :

SYNTAX ERROR

It must have something to do with BASIC not gicing control back to DOS.

Sigh

Thanks

Apple DOS 3.3 commands may require CTRL-D first
