[Ovmsdev] Debug logging via diag serial port

I wanted to get some direct debug logging. It took me some time to 
figure out the diag port only echoes what is sent from the SIM908 to the 
PIC18, I first thought it tapped RX+TX so I could see the complete 

Next problem was the modem switches echos off (after COPS I think), so I 
need to re-enable them at least once in a while.

I'm now using this scheme in can_state_ticker1():

     // CAN debug log via DIAG port SIM908 command echo:
     // ATT: could be a problem for running data transfers,
     //      should not be enabled for production/live firmware images!
     net_puts_rom( "ATE1\r" );
     sprintf( net_scratchpad,
             (rom far char*) "# ERR=%u SOC=%u RNG=%u SPD=%d PWR=%d 
             RXERRCNT, can_soc, can_range, can_speed, can_power, 
car_chargestate );
     net_puts_ram( net_scratchpad );

My questions: am I right with the suspected problem, and is there a 
better way?
