Workbench 1.3, serial console in shell

hadoque · 16 August 2019, 19:29

So I'm using an Amiga again for the first time since many years, and for curiosity I want to test out the serial port.

What I would like to do is the equivalent of linux screen:

Code:

screen /dev/serial 9600

, for example

is this possible in the amiga shell?

When running Amiga Explorer, you do:

Code:

Type SER: to RAM:setup

so I tried

Code:

Type SER: to CON:

but that didn't work. Since the Amiga Explorer thing works, I'm thinking that there should be a way to interact with the serial port through the console aswell?

Try AUX: instead of SER:

newshell aux: if you want serial shell.

mount AUX: ;if not already mounted
newshell AUX:9600/8N1

if I recall the path argument for AUX: correctly.

That should rather be:

Code:

type SER: to *

The name of the current console is "*".

Thanks, but none of the suggestions work:

Code:

>type SER: to *
Can't open SER:
>

First time I run newshell:

Code:

>newshell AUX:
>

Second time:

Code:

>newshell AUX:
Unable to open new window
NEWSHELL failed
>

If I run newshell after that, they are numbered 3, 4 etc. No number 2. Seems like the first newshell is created but doesn't show...

Of course that shows. It opens a shell on the serial line. If there is nothing connected to the serial connector, you don't see anything.

Of course. The serial output is now busy and occupied by the shell. If you don't end the shell there, nothing will happen.

Ok, well , how do I interact with the shell then? I get no new window like when I run newshell without parameters. Sorry, I just realized I didn’t make it clear that I don’t see a new shell...

Alright, now I get it. Newshell aux: opens a shell on the other end of the serial connection. That works and explains the behaviour.
But what I meant was to open a serial terminal on the amiga. I still can't figure that out.

You don't get a "new window". The shell operates on the terminal connected to the serial line. *There* you get the shell prompt. Not in a window. AUX: is like SER:, just line buffered. (So AUX: is to SER: what CON: is to RAW

.

Sure, but my original question was if it was possible to do this without a dedicated program.
