Forum Index : Microcontroller and PC projects : Terminal program on Raspberry PI?

What is the recommended terminal program to use with MMBasic (MM2 or PicoMite) on the Raspberry PI? Something that supports the function keys in the editor. Is there anything that supports XMODEM? Thanks Edited 2021-09-20 17:20 by matherp |

Almost always use PuTTY. Occasionally an old version of Rob's GFXterm; still haven't compiled up a new version. Best wishes, Tom Game*Mite, CMM2 Welcome Tape, Creaky old text adventures |

For XMODEM I resort to 'minicom' ... and then I have a lie down and a cup of tea with at least one sugar  Best wishes, Tom Game*Mite, CMM2 Welcome Tape, Creaky old text adventures |

So basically despite the wonderful open-source nature of Linux there is no comparable equivalent to teraterm which has been around for many years and just works? |

I use ser2net on the RPi and link to it with Teraterm in the comfort of Windows. Jim VK7JH MMedit MMBasic Help |

Hi Peter, I'm not a Linux guru, but that's about the size of it. Tera Term is exceptional and the closest that Linux has is PuTTY (which I think began on Windows?) I believe there are (unsupported?) forks of PuTTY that add XMODEM support but I'm not aware of one on the Pi. My suspicion is that the developers likely to develop such features are also the very developers who can make the command-line dance and so they don't bother - I think 'sx' is the command-line XMODEM program, but I've never spent enough time to overcome the activation energy and get it working. If/when MMB4L gets serial comms support (not in the first alphas) then you should be able to XMODEM from that to a 'mite - perhaps a whole comms package for communicating between Linux and the other 'mites could be built up in MMBasic at that point. Other solutions may be available - I believe @Jiri has something in Python ... which we all know is your other great love .Best wishes, Tom Game*Mite, CMM2 Welcome Tape, Creaky old text adventures |

What in particular does Tera Term have that makes it so fantastic and is lacking in programs people freely donate for use under Linux? Is it mainly XModem support? John Edited 2021-09-20 18:42 by JohnS |

Just looked for one and there doesn't seem to be a lot of choice if you want VT100 and Xmodem in linux. :( Edited 2021-09-20 19:12 by Mixtel90 Mick Zilog Inside! nascom.info for Nascom & Gemini Preliminary MMBasic docs & my PCB designs |

They're both a bit retro LOL I've programmed a lot of families of uP/uC devices and never needed xmodem in, er, 30? 40? years. (I vaguely recall using zmodem but not when/why. Would be decades ago.) I may well have used vt100 things but as I commonly use terminal emulators they would likely "just work". Other than that I suspect it would also be decades ago. It looks like there is/are xmodem program(s) so what happens when used? John Edited 2021-09-20 21:18 by JohnS |

mmbasic's expecting the wrong VT100 codes. minicom on Linux is sending ^[OP ... ^[OS for F1 ... F4, while mmbasic's expecting ^[[1~ ... ^[[4~. It's also swapped backspace and delete. These are fairly easily modified for the rather ancient putty for linux, but as other people have noticed, putty has no file transfer support. rx/sx support in minicom is okay, it's just a faff to get the right filename typed in before the other end times out. I use it all the time with various CP/M and 6502 machines I have hanging around. I'd much rather have zmodem's autostart support. Linux doesn't have PC-like terminal programs because it became popular just when direct dial-up comms were fading, say 1993-1995. It inherited all the Internet protocols from the start, so it made all the Trumpet WinSOCK nonsense in Windows look a bit noddy. (and this board, for some reason, doesn't like ellipses, which I had to retype as '...'. Most odd.) |

It looks like the function key codes are to do with the (apparent) fact that a VT100 didn't have function keys so much as PF1-PF4 and those are the codes for those. I don't know where the codes mmbasic expects for F1-F4 come from (VT220?). I guess minicom or maybe xterm can be tweaked for them. It's not really a Linux or VT100 issue... putty looks to be able to transfer files but I don't see any protocol as crude as xmodem. edit: oh, there's https://www.extraputty.com/features/xmodem.html picocom looks like it may be able to do xmodem. screen looks to have some sort of rz/sz support, nominally for zmodem but maybe usable for the cruder xmodem?

If you look at the downloads for ExtraPutty, they are all .exe, .dll files. Looks like windows only. PicomiteVGA PETSCII ROBOTS |

GFXterm supports all the function keys - the only thing lacking is xmodem support, and i am considering ways of adding that. no installation required, just download the single executable, set permissions to allow running it, and go. cheers, rob :-) |

Hi Peter, I have not found any linux serial terminal program that supports Xmodem. But you may be able to use the serial connection to emulate an ethernet connection using PPPD. Then the transfer of files becomes easy. Just FTP. pppd on a raspberry pi PicomiteVGA PETSCII ROBOTS |

Please could someone test the attached with minicom I think I've got to the bottom of it. MMBasic is using the X11R6 xterm codes and minicom is using the XFree86 xterm codes. These are the same except for F1-F4 and F13-F16. I've added in support for the XFree86 codes (completely untested) so if someone can verify it for me I'd appeciate it.

PicoMite.zip UPDATED 10:42 UTC File with <esc>OP rather than <esc>[OP etc. Shift F3 should now also work Edited 2021-09-21 20:39 by matherp |
