So call something like > fgfs ..... --telnet=foo,bar,100,foo,9999,bar ..depending on what data you drop into or ask for from the fdm, speeding up telnet _may_ also make you speed up the fdm so it _can_ properly solve the problems you feed it: --model-hz=n Run the FDM this rate (iterations per second) ..movie etc makers on slow irons may also wanna play with: --speed=n Run the FDM 'n' times faster than real time -- ..med vennlig hilsen = with Kind Regards from Arnt Karlsen ...with a number of polar bear hunters in his ancestry...
