Is com0 a reserved name ?

Is com0 a reserved name ?

[Rainford, Alan]

When I attempt to create a directory name com0 (no not for the device) I get
"mkdir: `com0' exits but is not a directory.  No matter where I attempt to
make the directory I get this message.  If I create the directory under the
windows cmd shell and then do a ls the directory will appear as
"crw-rw-rw-".

Yes, just like 'com1' 'com2' up to (AFAIK) 'com9', and 'lpt1', 'lpt2',
'lpt2', 'prn' and all those old-fashioned DOS-device names (sigh). This was
the case in DOS version 3.x (maybe even before), and still is in all windows
versions (for compatibility reasons in the respective DOS-boxes), again
AFAIK.
Years ago, this took me two days of debugging; they've been more than made
up for by being able to guide several younger colleagues since then, however
;-)
