More com ports for PPT?

[Jerry]

PPT will automatically connect to a com port if it is in the
range com1 to com4 (I think) but not higher than that. Is it possible
for you to modify PPT to look for a connection on ports as high
as 14? I realize you can add the line PORT_PPT = x, but we
have several computers that run the same script over a
network, and they have different numbers of com ports.
