Thank you for the attached documents. Document "iOptron iEQ45 RS-232 COMMAND LANGUAGE November 22, 2010" is correct for Ieq45 with 8406HC.
It confirms that the appropriate commands for the pulse guide are like "Me999#" .

I do not have much programming skills but I will try to improve the driver.

Comands Me# and Mw# dosen't works corect. There is bug in the firmware. Ioptron will never fix it. I think about workaround. Maxim Dl uses small goto for move by arrows.

Could You check commands :SE?# and :SE# ?. My mount does not respond to them.
