GSFileHandle doesn't work on Serial Ports

[Marc Brünink]

Hi,

in [GSFileHandle read:length:] we use a read() system call. If I 
understood it correctly read() blocks until the requested amount of 
data is read or special circumstances raise (e.g. EOF). On a steady 
serial  connection there's no such thing as EOT. Therefore 
[NSFileHandle availableData], [NSFileHandle 
readInBackgroundAndNotify],... block until READ_SIZE bytes are read. 
I've seen this on Windows XP, Solaris 10 and I belief on debain sarge, 
too.

Fortunately we've readDataInBackgroundAndNotifyLength:    :-)

I'm not on the list.

regards
Marc
