reluctant to read win95 directory (PR#231)

[John.Peters@tip.csiro.au]

Using rw0642 under win95, on executing from a directory on the c: drive:

   system("command.com /c dir", intern=T)

there is a whirring from drive a: (empty), then the message appears in a 
dos box:

   General failure reading device aLP!!?
   Abort, Retry, Fail?

Repeating the command a few times finally results in success with no 
whirring, after which there are no failures (even after restarting R) 
until the computer is rebooted. 

The computer is on a TCP/IP network with slow automounting, though the c:
drive is of course local.  It is set to try booting first from drive a:.

Could this be a timeout problem which could be fixed either in R or with
some setting in win95?

Thanks for R
