While that's a good thing to do, i'd say it's completely wrong in this
instance.

using a #define to enable hayes ESP support is ... a hack, and a
broken one at that.  hayes ESP boards should be included via seperate
devices (sharing the back-end code that implements most of the driver,
of course).  The way the ESP probing code works in com.c is ... "very
wrong."
