Mariano DM Posted June 16, 2019 Share Posted June 16, 2019 I'm trying to communticate to tcpser in my pi via RS232. Although I loaded the alternate driver HSMOD v6. It seems I cannot get any communication, tweaked both sides to same settings (9600 baud, no flow, no parity). I can even see the settings in the control panel, but no data passing through. Do you know if it requires a null modem cable instead of just a gender changer? Thanks. Quote Link to comment Share on other sites More sharing options...
snarkdluG Posted June 16, 2019 Share Posted June 16, 2019 (edited) 2 computers without modems needs a null modem cable to be able to talk to each other. It flips some wires in the cable, for example the send is connected to receive in the other end, handshaking, carrie detect and so on.

Mariano DM Posted June 16, 2019 Author Share Posted June 16, 2019 Guess so, but in the Pi side I’m running a modem emulator. It responds to AT commands. My concern is that both the cable and the Atari DB25 connector were male adapters. Probably I’ll have to test the pins to make sure it matches Quote Link to comment Share on other sites More sharing options...

Bikerbob Posted August 10, 2019 Share Posted August 10, 2019 So on your Pi are you just running Raspbian and then TCPser on it?? is there any config you could share? James Quote Link to comment Share on other sites More sharing options...
Mariano DM Posted August 10, 2019 Author Share Posted August 10, 2019 Sure! Correct, you don’t even need full raspbian, any small server will do. I think the only special thing I did was to disable the flow control. &K0 I followed this guide https://www.insentricity.com/a.cl/215/putting-your-retro-computer-on-the-line And this, but usb instead of UART http://podsix.org/articles/pimodem/ Quote Link to comment Share on other sites More sharing options...
Mariano DM Posted August 10, 2019 Author Share Posted August 10, 2019 Plus, I can use it for both the ST and 8bit. Now if I could find a RS232 interface for Spectrum;) Quote Link to comment Share on other sites More sharing options...
