<br>
Experiencing the wonderful world of 9600bps that I had unfortunately missed out on. It is so beautiful and relaxing. I am sure my BP is dropping quickly.<br>
<br>
Anyone on HECNET running OVMS 7.3 or later can try to wait for the world to (a) finish spinning and (b) move across the screen while spinning:<br>
<br>
$ P9600BPS="$QCOCAL::DUA2:[FAL$SERVER]9600BPS.EXE"<br>
$ PIPE TYPE QCOCAL::GLOBE.VT | P9600BPS <br>
$ PIPE TYPE QCOCAL::MOVGLOBE.VT | P9600BPS <br>
<br>
Granted HECnet delays are added to 9600 BPS.<br>
<br>
Best,<br>
Supratim<br>

<br>
thanks. basically trying to write a simple program to filter the old VT100 demo text files to slow them down (calculate the required usleep()).<br>
