Add one more check to ensure minimum count is met

[knro]

When sending commands, sometimes we receive response from another command in the buffer despite flushing the buffer. So in case the response does not meet the minimum count then we retry.

Hi @knro I am also having the same error message when using Wifi connection on my CEM26 as reported earlier:

[2023-09-25T18:01:01.845 PDT INFO ][ org.kde.kstars.indi] - iOptron CEM26 : "[ERROR] Error setting RA/DEC. "
[2023-09-25T18:01:46.918 PDT INFO ][ org.kde.kstars.indi] - iOptron CEM26 : "[ERROR] bool IOPv3::Driver::getCoords(double*, double*, IOPv3::IOP_PIER_STATE*, IOPv3::IOP_CW_STATE*): Expected 20 bytes but received 23. "

Is there a modified driver with the fix that I could test on my system?

Thanks!

Can you please check both wired and wireless connections?

Hi, I checked the wired connection, and it appears to work the same as before with the original driver. I did not see any noticeable lag or delay in the start or finish of a slew to any of the targets, wired or wireless. Hope that helps, Thanks!
