DOS copying files / drive to drive.

February 14, 2011 at 07:52:37
Specs: WIN 95
I have an old DOS desktop that floppy drive and network interface are bad. I need to copy files onto another computer. Is there a way to copy from one serial port to another? Or is there any way to recover these old files and applications?

You can use a serial port connected with a Null Modem cable. A Null Modem cable is the RS232 Serial equivalent of an Ethernet crossover cable.

You can then copy the files using Hyper-terminal on the Windows machine and any number of MS-DOS communications application. I cannot remember if MS-DOS came with any communications applications, it is that long since I have used it.

Probably a mush easier way, and quicker way, would be to remove the hard disk from the MS-DOS machine and temporary install it in the Windows machine. There is no reason why it shouldn't work under Windows 95.

Stuart; thank you very much. that is what I've been telling our shop's computer wiz but I couldn't remember all the details. course I like your second suggestion but we're taking the info from a desktop and putting it in an old laptop.

Thanks again

I thought NUL Modems only worked at 9600 bps. This would take forever to backup this way. Yes I think pulling the drive and sticking it in another machine is way better.

I stand corrected you could get 115 Kbps...

Still very slow if we are talking about a hard drive larger than 100 MB

The Speed a Null Modem is dependent on the UART in each machine. It can be as high as 116Kbs+. When you think about it has got tot be at least as fast as a 56k Modem and probably faster as there is no modulation involved.

As the OP is transferring from a desktop to a laptop, transferring the hard disk is not possible. Another possible solution is to purchase a USB enclosure and put the hard disk in that.
