ASCII Instructions 10-21
When the program scans the instruction and finds the Done bit (DN) set, the
processor then sets the Synchronous Done bit (EM) to act as a secondary
done bit corresponding to the program scan.
The Error bit (ER) is set during execution of the instruction if:
• the modem is disconnected (control line selection is other than NO
HANDSHAKING).
• port is in System Mode and is configured for DH-485 or DF1 Radio
Modem.
• the Unload bit (UL) is set. The instruction stops executing, but received
characters are sent to the destination.
• an ACL to clear the send buffer is executed, removing the AWA
instruction from the ASCII queue.
Using Inline Indirection
This allows you to insert integer and floating point values into ASCII strings.
The Running bit (IN) must be set before the string value can be used.
The following conditions apply to performing in-line indirection.
• All valid integer (N) and floating point (F) files can be used.
Valid ranges include 7, 8, and 9-255
• file types are not case sensitive and can include either a colon (:)
or semicolon (;)
• positive values and leading zeros are not printed. Negative values are
printed with a leading minus sign
