Sim800l odd responses

-

hi
i tried sim800l module uno no luck. test connected laptop via pl2303 serial/usb converter. @ command bunch of different responses: ok, [no response], rdy , "ý" (ascii 152) character. returns current network sim registered send same command again, respond error or unexpected result mentioned above.
i used 3.7v lipo battery , tested current , ok. tried different baud rates , resistor voltage devider on rx pin tried software flow control on , off, still don't know what's wrong.
your appreciated.

you have hardware didn't post link connected pc using device/circuit didn't post link to/a schematic for, , send somehow device, , or not expected response.

what, exactly, arduino question?

Indesign and MathType fonts

i having trouble getting indesign recognize mathtype fonts.  have been told move mathtype fonts on 2 indesign font folder.  copied mt-extra font file mathtype folder , pasted indesign font folder.  nothing changed.  indesign still gives me blank box after copy mt-extra font mathtype -->illustrator-->indesign.   guess need instructions on how transfer of fonts done correctly.  i'v looked @ install fonts manual indesign, not clear me on how it.  need utility fontexplorer this, or there other way.  what's weird working fine until had reinstall osx , reinstall cs3, font trouble started.  need toggle "activate-reactivate' adobe cs3 , don't know how close 20 max on this, worried that.  (i suspect because of note on forum might necessary).  thoughts appreciated. i'm using windows, advice may worth nothing...   1) shouldn't have deactivate id recognize fonts. 2) design science gives fonts away in type 1 , truetype flavors....
