mTCP NetDrive: network attached storage for DOS 2.0 or better

[mbbrutman]

The next version of mTCP NetDrive is available. This version (2024-02-18) adds support for multiple drive letters so you can connect to several images from different servers at the same time.

• If you can use FAT16B you can add up to 48 GB of storage across 24 drive letters. (FAT12 users are limited to 768MB.)
• Each additional drive letter costs 96 bytes in the device driver and 48 bytes in DOS. Even fully maxed out it requires only 9KB of RAM + the space for the packet driver.
• No changes to the server side .. everything is compatible.

See http://www.brutman.com/mTCP/mTCP_NetDrive.html for details.

Thanks. This was my first device driver for DOS, and it was quite a challenge. There was lots of software archeology to do.

You are so great. Your tools I use every time I am doing retro computing. Thank you so much to contribute your tools to the community

Thank you for the kind words, but let's not go overboard. ;-0

Over the past few weeks I've been working on the following changes:

• Debugging strange problems with 3Com packet drivers; there are two different 3Com cards that just behave poorly with NetDrive even though they are fine with mTCP. One of them really hates it when I send a packet while an interrupt is active, and I suspect there is a bug in the packet driver.
• Adding an "undo" feature for DOS. Imagine doing a bunch of work, deciding you didn't like what you did, and then just running a command on the DOS side to put the remote drive back to an earlier state in less than 5 seconds. You can see a preview of that feature here:

This feature is so great. Thanks a lot brutman.
