#Dosbox raspberry pi 4 serial

usb 1-1.2: FTDI USB Serial Device converter now attached to ttyUSB0

ftdi_sio 1-1.2:1.0: FTDI USB Serial Device converter detected To see what device was assigned to your adpater type 'dmesg' at the Linux prompt after plugging the cable in. Remove all other USB to serial adapters and plug in the FTDI programming adapter first.

If you have other USB to serial adapters plugged into your Pi the adapter may show up as ttyUSB1,2,etc.

#Dosbox raspberry pi 4 software

This is preconfigured in the software as ttyUSB0. The FTDI USB to serial converter should be plugged into the Pi. They are meant to be run from an ssh connection with an X11 server as descibed later in this document. Do not attempt to run dosbox or any of the DOS programs at the Pi end. This completes the programming of the Pi's software configuration. If you can it is best to cut and paste each line separately to the Pi Linux prompt. It is important that these commands are executed as shown. Then execute the following commands at the Linux prompt -Įcho 'AddressFamily inet' > /etc/ssh/sshd_configĮcho 'X11Forwarding yes' > /etc/ssh/sshd_configĮcho 'X11UseLocalhost no' > /etc/ssh/sshd_configĮcho 'XAuthLocation /usr/bin/xauth' > /etc/ssh/sshd_config

#Dosbox raspberry pi 4 download

If you want to use an exisiting old RIB box and cable it may not work unless it is self powered as the FTDI cable may not supply the required current.Īssuming you already have a configured hamvoip V1.5 system that has been updated to the latest version you will need to download the dosprogs package from the hamvoip repository using the following command at the Linux prompt. Make sure you get a 'ribless' cable, one with RS232 to TTL conversion in the cable. Google 'Motorola Programming Cable' or try this link. Motorola Radius Maxtrac GM300 M1225 CDM1250 CM200 CM300Ĭables for other radios are available.

Programming cable DB9 to Radio - Choose for your radio - Maxtrac and others.

Clone FTDI chips may work but have not been tested. This MUST be an FTDI cable, Prolific, etc.

True FTDI USB to 9 pin serial adapter available at Amazon.

Raspberry Pi with updated hamvoip V1.5 software, additional package download required.

Here are the suggested parts required for programming

Be aware that this uses a supplied custom compiled dosbox which works with the FTDI controller to supply the required custom baudrates that the Motorola radios require. All timings and configurations have been preset and so far have worked with all tested radios. The Motorola programming packages run under this MSDOS environment.

#Dosbox raspberry pi 4 install

Because it was not desirable to install the entire graphics package in the hamvoip installation, which would be necessary to run DOSBOX directly on the Pi, we instead do X11 forwarding to an X11 server where the program is displayed. The Raspberry Pi is an excellent platform to do this as it is readily available and provides a consistent environment to run the code. The hamvoip programming package uses dosbox a program to simulate MSDOS. This also could add the ability to program a radio at a remote site without being there. This works on the hamvoip Archlinux installation and can be used in conjunction with a running Allstar system in fact I have used a node on the same server while I was programming without any problems. Most would either not have the software or proper hardware.īecause of this we have implemented a novel approach that should work consistently using a Raspberry Pi, the hamvoip software, and a couple of inexpensive cables. It was widely accepted that you would need an old slow computer with a dedicated serial port to do this and trying anything else either did not work or was very finicky. One of the sticking points of using these radios has been the programming which required access to the software and more importantly a computer and hardware that was able to do it.

Since the commercial changeover to narrow-band some years ago a great deal of the now unusable commercial equipment is available to the amateur community. For many years hams have been using Motorola commercial radios modified for amateur radio use.
