I finally found my dummy load, so I can test the transmitting of pk232guru.

Well, it is transmitting, but I’ve yet to determine when it’s done transmitting to switch automatically from Transmit to Receive.

I’m sure the PK232 is sending some sort of status back, or else I’ll have to figure out how to query (called hpoll internally) the unit to ask if it’s done.

The fact that it’s actually transmitting made me quite happy.
