5.15 Serial Interface

The PICMG COM.0 specification revision 2.0 defines two optional 2-pin serial interfaces on COM Express® connector
pins A98/A99 and A101/A102 formerly used for 12V VCC input. Both new interfaces are available directly on optional
pin-header J83 and J84.

J78 and J79 allow both interfaces to be used as 2-pin RS232 interfaces COMA and COMB with Kontron Adapter cable

KAB-DSUB9-3

. Please check the documentation of your module if this interface is supported and how to configure.
