The problem is in type_cmd() maybe in QueryIsDevice?(). But currently I do not understand it. Have to take another look if I've more time...

[andi.b]

Experimental code in 3.05rc4 to address this problem. Feedback appreciated especially for side effects on 'normal' type.

Thanks for your work.
type alsahlp$ works fine here.
e:\browsers\cz[0]type wrnd32$
ERROR

Checked on cmd.exe to make sure it wasn't a problem with wrnd32$ and it pulled information from there fine.

[andi.b]

I've increased the buffer size to 4096 which is the min. size for which current wrnd32$ returns meaningful information. This is the best I can do in 4os2. With smaller sizes (used with type /P or /L options) wrnd32$ returns 'ERROR' or simply 'E' instead. This is a limitation of the driver and can not be easily worked around in 4os2. Same problem with some older versions of alsahlp$. See readme.1st for additional information.
