Below is a copy of an earlier message from Keith Petersen about P2DOS.
This DOS (version 2.1 at least) has many attractive features. You have the
full source, so you can tailor it as you wish. It supports time/date
stamping of files in a CP/M3-compatible way. It has a search path, like
that of ZCPR, but unlike the latter is useful when a running program looks
for other files, such as overlays, swap files, libraries, and so on. One of
the troublesome limitations of ZCPR is that it can find the main COM file,
such as WS.COM, along the search path, but then when WS looks for its
overlays, it can't find them and the program grinds to a halt. There are,
of course, other solutions to this problem. P2DOS now also supports the
archive bit so that modified files can be identified. The one feature that
ZRDOS has that P2DOS currently lacks is the ability to automatically log in
new disks.

A Z80fied BDOS replacement, has a public file and DOS-level search
capability, supports time-stamping and RTC setting. Supplied with a
preconfigured ZCPR2 CCP. All source code and ZEX file for
assembly/installation included. Requires M80/L80, not hard to adapt
to other assemblers. Other new features of P2DOS include testing of
console status after 256 characters output. Error routines give
more information. Public files are supported, you can access a
public file from any user number. File R/O error message occurs if
Public, File R/O, and System files are active. Disk size can be as
large as one gigabyte. File size can be as large as one megabyte.
If you are unable to access SIMTEL20 because of network restrictions
please remember that MOST of the new files announced to Info-Cpm are
also available on my RCP/M Royal Oak (MI) which may be accessed at
300 bps (Bell 103a), 1200 bps (Bell 212a), or 2400 bps (V.22 bis).
The telephone number is (313) 759-6569. They are also available from
the CP/M RoundTable on General Electric Information Services' GEnie.
