Re: [Freedos-user] Serial port WiFi modems - was: MS-DOS 7.1
The various Wifi232 variants seem to run about $45-$100USD. I think the PiModems w/a $10-$15USD PiZeroW could be made cheaper but no one seems to be producing prebuilt versions.

[Freedos-user] Serial port WiFi modems - was: MS-DOS 7.1
Hi DOS people, those links from Louis are really interesting! For example the Guru Modem is a device based on the tiny ESP32 WROOM computer (actually sold as controller for WiFi and Bluetooth, but has plenty of CPU power) which has a serial port to connect it to your PC and has some modem simulation software installed. For the PC, it will look like a classic serial RS232 dial-up modem, but it will use your WiFi to connect to the internet, instead of actually connecting your computer to any phone line :-) As Louis has suggested a whole collection of links to various similar products, I wonder which of them are pre-assembled and which have to be assembled by those who buy them? Also, what are the prices? Have DOS users already tested the products? Which ones would you recommend? The general idea is very cool, although LAN is of course much faster than RS232. Regards, Eric PS: I guess 5 Volt from your USB port should have enough power for the Guru Modem? Or use a charger. ___ Freedos-user mailing list Freedos-user@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/freedos-user
Re: [Freedos-user] Serial port or USB/PCMCIA modem support
It might be possible to get a PCMCIA card working, depending on the particular hardware. Most likely, you would need a set of card and socket services DOS drivers for your PCMCIA chipset and a true PCMCIA card (rather than the newer Cardbus type, which almost everyone seems to refer to as PCMCIA also).

Re: [Freedos-user] Serial port or USB/PCMCIA modem support
My DOSUSB driver comes with support for USB-Serial adapters. However DOSUSB does not emulate an UART and therefore will not work with many DOS communications programs. You will have to change the application program to either support the DOSUSB URB/API or use the included serdrv.sys device driver which allows to use DOS calls to communicate with the adapter.

Re: [Freedos-user] Serial port or USB/PCMCIA modem support
You don't say whether you want to run FreeDOS on the bare metal or in a VM. My suggestion would be that if you already have Windows on your laptop it's quite easy to run FreeDOS in a VM, then you can connect the USB port using Windows and set it up as COMx inside the VM, then you don't need to worry about DOS drivers for USB. If you are writing your own application I suggest using a FOSSIL driver like BNU inside the FreeDOS environment rather than re-inventing the wheel of interrupt-driven communications.

Re: [Freedos-user] Serial port or USB/PCMCIA modem support
You can buy a USB-to-serial adapter that plugs into your USB port and provides a serial port. I don't know if FreeDOS provides drivers to support USB-to-serial adapters but they exist. There are online stores that sell these adapters in great variety -- the chipsets used to support them vary, and at least one online store will identify the chipset for each of the adapters sold. Again, and to be clear...I do not know if FreeDOS supports these adapters. Bob Cochran On 9/2/12 10:52 PM, Aman Singer wrote: Hi, All. I have a laptop on which I would like to install Free DOS.

Re: [Freedos-user] Serial port or USB/PCMCIA modem support
Adding to Mr. Cochran's remarks, the USB to serial porthttp://en.wikipedia.org/wiki/Serial_portusually is a 9-pin like the ones provided on the IBM PC AT. The Wikipedia article Serial Port http://en.wikipedia.org/wiki/Serial_port has a picture of a USB dongle. It is a good source for background information. Dongles usually requires a Windoze software driver to make it usable as a serial port. There would be a need for it to have a similar software driver for FreeDOS. That last statement is where the issue sits.

[Freedos-user] Serial port
Hello, I have an external speech synthesizer that I have been fooling around with on my host os. Mac os x 10.7 lion. In order to use the synthesizer on my mac I had to get a usb2serial adaptor and install it's driver. The driver is based off of the ftdi chipset. My usb2serial adaptor is located at /dev/cu.usbserial-FTKVMAFF on my mac. I have used this path to send text to my synthesizer. I have virtualbox and freedos running as a guest os. There was a utilities disk that came with the synthesizer, and I have copied some programs to my freedos c drive. I wanted to run some of the utilities programs so I hooked up my speech synthesizer connected to my MacBook pro laptop via a USB port, I am using my usb2serial adaptor. And I have my synthesizer turned on. There is a test program included with the utilities. And when I run it it says my synthesizer is not working properly. I have a doubletalk lt external synthesizer. And like I said I verified that it is working. In the manual for the synthesizer it says, that you pro ally don't need to install any additional software. Although there are some special drivers like for windows 98. I am wondering how to set up my device in virtualbox to work with freedos? I have looked in the settings for my guest os, freedos. I see under ports a section on serial ports, and also a section on USB. But I don't know which would relate to my external speech synthesizer. I did click on the little USB icon when freedos was running and my usb2serial device was listed but when I checked it a virtualbox window popped up saying something about an error. I think it referred to ioctl but I can get more info on the exact error. Anyway, I just wondered if anyone had any info or help on getting my speech synthesizer working?

Re: [Freedos-user] Serial port
Hi, If I followed all this, I would start by checking the usb aspect itself. likewise, just as an extra test, can you connect the synthesizer directly to your box, as in is there a serial port working on the box running freedos? that too would help isolate the problem. if it works fine without the usb factor, the issue is with usb itself. hth, Karen On Wed, 7 Sep 2011, James Collins wrote: Hello, I have an external speech synthesizer that I have been fooling around with on my host os.

That is rather a problem with VirtualBox (or pretty much any VM host software). VB has to properly translate the USB (or in this case USB2serial) device into a true serial port within it's environment. FreeDOS or any other client OS within that VM simply won't know anything about that device in the first place. Had similar issues while getting a parallel port printer in DOSBOX working on Windows 7 Home Premium/64Bit. DOSBOX just would not provide a proper translation from the Windows 7 parallel port device to a plain DOS parallel port within DOSBox. Different host OS, different VM but same general problem...

Using a not very hardware friendly host OS is certainly not helping here, which is likely to even further limit the chances of finding a working solution...
