Are you sure Brian?  I am running Cygwin on WinXP, and using stty on 
/dev/ttyX fails,
whereas on /dev/comX  it works (where X is valid of course).

Similarly open("/dev/ttyX",O_RDWR) returns -1, but returns a valid file 
ID with open("/dev/comX",O_RDWR).

My understanding is, that on a PC, psuedo-device files of the form 
"/dev/ttyX" do not exist?

At any rate, the code has been working for two months using the 
/dev/comX naming convention.

regards,

David le Comte
