Should "devices.in" really have a limit of 16 "/dev/com" ports when the 
"ttyS" ports are allowed up to 64 values (max of 63 since it is a 
zero-based index)?

I changed the upper limit on the "com" range for 1.5.25 to "64" along 
with the "ttyS" range and it compiles and allows using the "/dev/com" 
aliases above 16 ports without a problem.

Yet when using a recent snapshot only "ttyS" ports work above the 16th 
port. The "/dev/com" identifiers beyond "16" do not open.
