Oricutron and Euphoric with Modem.dsk and RS232

Post by jdavis6809 » Sat Apr 18, 2015 11:53 am

Hello,

I have tried to use both emulators (Oricurtron and Euphoric) with modem.dsk to connect to the pc com port (com 1) tried four machines 2 with win7 and 2 with xp

with pin 2 and 3 connected together on the 9 way dtype

I know you have to edit the config file which I did

for Oricurtron config set to loopback

when I type a character none is returned

Both emulators state they emulate the acia 6551 and is hocked to the pc com port

Also not sure that modem.dsk works ok or not

Is there a tap version for this software or not? unable to locate.

Is there a tool to convert .dsk to .tap?

Once I know that this works I will build a serial card for the oric atmos

Regards

Do you have the machines set up with a Windows terminal, and the chars are received that way across the link, first? This should be verified.

Apropros serial i/o on Oric, I'd love to have working MIDI, which would give a rudimentary networking protocol as well, sufficient to the Oric's needs - i.e. it could be feasible to have a MIDI SYSEX transfer happening to 6 Atmos' wired up to a single Telestrat, with each SYSEX being a new app/tap/dsk to send over the humble wire. I do think the Oric can do a TCP/IP stack, but my interest in MIDI is musical as well. A stack of 6-Atmos in unison mode might sound ridiculous.

Hello,

Yes forgot to add using real term on pc (that's not required yet, that's next after loopback works)

What I am doing is loopback so modem.dsk terminal should send character then read it back and it does not

Hope that makes things clear

Oricutron v.1.2 works fine using serial emulation in 'loopback' mode with MODEM.DSK.
After booting with MODEM.DSK you have to configure the hardware (i.e. 1.SETUP LINE).
Than select 9600, 8 bit, no parity, 1 stop bit.
Importatant: base address is #31C!
Flow control is 'none'.
Start the terminal program (i.e. 2.RUN COMM PROG FROM DISK)
Here is how I use it under Linux (in Windows it should be the same!):
Starting emulator from command line:
# ./oricutron -ma --serial loopback disks/MODEM.DSK
serial1.jpg
Then every typed charachter is echoed back:
serial2.jpg
@jdavis6809: is there any special reason to write your messages with so much empty lines - I'm just curious ;)

hello,

Spaced lines easy for me to read.

I think you misunderstand me.

I want to loopback via com1 port of the pc (pins 2 and 3 of the 9 way dtype connector) within the modem.dsk program.

As you outline config is set to loopback

part of config file for acia

; ACIA emulation back-end name:
; 'none' - no serial present
; 'loopback' - for testing - all TX data is returned to RX
; 'modem[:port][:ipv6]' - emulates com port with attached modem,
; only minimal AT command set is supported and
; data is redirected to TCP. Default port is 23 (telnet).
; if :ipv6 is added at the end uses IPv6 instead of IPv4
; 'com:115200,8,N,1,<device>' - use real or virtual <device> on host as emulated ACIA
; baudrate, data bits, parity and stop bits can be set as needed
; ex.: Windows: 'com:115200,8,N,1,COM1'
; Linux: 'com:115200,8,N,1,/dev/ttyUSB0'
serial = 'modem'

I tried all settings listed above

nothing works

regards

Now it clear what you want to do. Put in config file:

serial=com:115200,8,N,1,COM1

Take care to set the proper number after the up-case 'COM', you can check in Windows 'Device Manager' the actual number.
Than plug loopback dongle in your RS port. Here are variants of what you need:

or
rs-dongle-1.jpg
rs-dongle-1.jpg (11.66 KiB) Viewed 3554 times
Setup the program as described in my above post.
There is no relation between selected COM parameters in Oric and the parameters for the real COM.

Happy loopback-ing ;).
