Get Last Error Code

\i ? E

Returns the error code of the last executed command.

When a command is successfully executed, the error code is set to 0x0. Therefore, retreiving the error codes only makes sense immediately after a command returning [NACK].
Refer to Error Codes for a complete list of possible errors.

Response:

[ACK] string::error [ACK]

Parameter	Type	Range	Description

Response Example

[NACK][ACK][03][F1][ACK]

This example returns [NACK] as a response to the Set Font command and the error code 1009 (0x03F1) which means "Font not found" (see Error Codes).
