bug in COM communication

Hi
I tried to connect Ham Radio Deluxe (HRD) with SDR Console (SDR) with no success. Then I monitored the traffic on the COM ports and saw:
com6Monitor1.xlsx
(12.84 KiB) Downloaded 187 times
After a request of HRD on the COM port SDR sends its answers from a one-byte buffer. This does HRD not accept.
To prove this behavior I wrote a little python wrapper
Port Monitor.py.txt
(1.37 KiB) Downloaded 186 times
which combine each (SDR) sent phrase into a string. And voillĂ : It works (even without OmniRig).
Issue SRD: do not change the the string length to 1 while answering on COM port.
73 de HB9HCI, Andreas
ps.: HRD has a nasty issue: max freq.<2.147.483.647Hz

Hi,
  • HRD must be set to TS-2000.
  • Please use the serial port monitor so I can see what's happening use this link.

Thank you for your request to prove it with your port monitor: now everything (on your site) works as expected!. (Surprise for me!) Even without OmniRig.
