I gather that DOSBox will not work with AALib? This is from what I have read and: pi@raspberrypi ~ $ SDL_VIDEODRIVER=aalib dosbox DOSBox version 0.74 Copyright 2002-2010 DOSBox Team, published under GNU GPL. --- Exit to error: Can't init SDL Unable to open a console terminal
Is it possible to run DOSBox in BSD/Unix text (console/tty) mode?

Is it possible to run DOSBox in BSD/Unix text (console/tty) mode now? If it is, ideally I would like to also try dosbox with https://github.com/shellinabox/shellinabox which uses java, and a built in mini ajax webserver, to serve any command line tool as a web page. It works incredibly well with SSH …

Necroposting I know, however Databases really went backward IMHO, with the shift to GUI. I'm looking at OpenOffice Base and MySQL front ends, however none even come close to what Paradox PAL (or DBase for DOS) could achieve with some relatively simple code. Give me a sequential language any day ( …
Re: Accuracy of emulated RTC time

Ah yes, thank you for refreshing my memory from my PCDOS days.....

I will update this thread in a few days time once I have time …
Re: Accuracy of emulated RTC time
Posted on 2015-12-18, 10:45
I would like to add that the RTC was not available on the PC and XT models, and was introduced on the AT. So there's a good chance that software doesn't try to read the RTC directly, but uses DOS time functions instead, because this is the more compatible and common way to handle time in DOS (in …
Accuracy of DOS clock
Posted on 2015-12-13, 11:04
For applications that utilize the time, like BBS software, how accurate can the RTC emulation be? How many seconds or minutes per hour will generally be lost? Are there any ways to improve emulated RTC accuracy?

See my posts in other threads regarding carrier detection. It appears that DOSBox is supposed to pass DCD assertions from the host to the direct connection, however I have used various UART reading utilities and can confirm that DCD changes (in Raspbian Linux at least) are visible in Linux but not …

Well, I've been back on this issue and decided to take a look at the serial port code. I am not into C (yet) however, I can see that the DCD bit of the emulated 16550UART is at least considered,.. however it does not work for me. …

Re: Reading Modem DCD Status with USB to RS232 under Linux

I see the some people have installed a real DOS in DOSBox such as M$DOS. Obviously this cannot change the emulated COM port hardware, however would it not bypass some of the DOSBox code that talks to the emulated hardware? Then the question is which DOS? PCDOS, DRDOS, FREEDOS? Perhaps one was better …

I know this refers to the 5 bit topic, however I'm wondering if changing from 5 bits only would assist in reading DCD: "Many USB serial ports do not support a 5 bits per byte configuration however when configuring a serial port under DOS it is fairly common practice to simply set the serial ports …

Re: 8 bit PCM to 16 bit PCM adapter
Posted on 2015-07-14, 10:57
8-bit u-law is actually a sort of compression algorithm, so your raw samples are more than 8-bit linear PCM (probably 14-bit). What you probably need to do is u-law decode it (which I believe can be done with just a lookup table), and while doing that, you can promote it to 16-bit linear PCM. Yes, …

The DAC is a TCM128T16N, which is mainly used in telephony applications. It sends/receives u-law encoded PCM. So I'm trying to add SPDIF to a device with 8 bit u-law encoded PCM.
