Cpmtools doesn't work as expected

Description:
Cpmtools[1] 2.23 built in MinGW.
For IBM-3740 format images from Z80Pack[2], cpmls works well but cpmcp add extra 0s (IIRC three extra zeros in every occurrence) in the middle and at the end of the file.
For 88-DCDD format images from Z80Pack[2], even cpmls doesn't work well.
Other notes:
AltairZ80[3] in SimH[4] has R.COM and W.COM which can be used to transfer files from/to host PC (Windows for me).
Altair Tools[5] can be used to copy files from/to 88-DCDD images.
AltairSim in Z80Pack[6] do have R.COM and W.COM, but I failed to build a workable Z80Pack 1.37 in Cygwin while the prebuilt binary for Windows is too old.
I'm emulating Altair 8800 for historical interest. Thanks all for providing all these emulators, manuals, tools, builds, guides.

I just had a look, I have installed cpmtools 2.20 on OSX from the source tar ball, which doesn't have such

a problem. Don't know what the problem is in 2.23 though.

The old Windows binary is not supported anymore, that was build on a Windows XP system years ago.

It works now, built in Cygwin. That shows incompatibility with MinGW.

Now it works. The problem is, the speed of copying files is only about 20 bytes per second in MITS format CP/M.

I'm running `mitscpm22` in altairsim of z80pack 1.37, built with no changes. And system.conf is modified, `tarbell_rom_enabled` to 0, `boot` to ff00. I copied LS.COM (4K) R.COM (2K) W.COM (2K) to other disks several times, all in low speed (from 50 seconds to more than 3 minutes).
And running `cpm22` seems in normal speed.

in iodevices/altair-88-dcdd.c.
The Tarbell controller doesn't emulate correct disk timings, the mechanics move in zero time, so software
seems to run faster.
