connect a laptop with a terminal program to the serial port as a "teletype replacement"...

Hi,

I used this Phoenix device with an ASR33 Teletype at 110 Baud, using the special firmware that Fred had made then.

Hello Detlef:

Using the RS-232C port am I correct in noticing that if I hit CR or I hit LF the port will give CR & LF?
I seems to be getting this in the Teletype TT-15
Thank you

Also when I send BELL (FIGS J) <'G> is printed. Is this from I-TELEX?

[detlef]

BELL is sent als Ascii-Code 07 (Ctrl-G).
CR is sent as Ascii-Code 13.
LF is sent as Ascii-Code 10.

If you are testing with a terminal program, it might do some conversions.
Most terminal programs can be configured to convert CR to CR/LF or LF to CR/LF.

Hello Detlef:
Thank you for your message.
I am not using any terminal program. I think I-TELEX will send to the local printer < ' > for a <CTRL> code sent.
In addition I think it is programed for CR and LF if either CR and LF is selected.
It's fine, now that I know *smiles*.
Thank you

I tested it with Tera Term connected to the serial port and wrote the received characters to a binary log file.
I called the number of my serial card with a Siemens T1000 and sent BELL, CR and LF and that's what I see in the log file: 07 0D 0A.
There was no conversion done by the serial card. And when I send BELL the terminal program beeps.

How do you look at the characters coming from the serial port?

Hi bambi,

if you do not like to have a Laptop, or Computer connected to i-Telex, you can use a Raspberry Pi zero and a small monitor.
The software is "bare metal" that means you do not have to shutdown the Pi. Just switch it off.

You can find the software here:
https://github.com/fbergama/pigfx
You also need a converter, or level shifter:

It is running very well and stable.
