CHAPTER 2
MODES OF OPERATION
Revised: 15 Oct 03 2-3 EST P/N AA104
SEMI-TRANSPARENT MODE
This mode should be utilized when sending a non-ASCII file and there is a possibility that the SENDPAC character could be
contained in the transmitted data set. Perform the following prior to programming the ESTeem to initialize the unit to factory
default settings:
1. Turn Bit 2, OFF on the RS-232C Setup Switch.
2. Reset the ESTeem.
3. TYPE FA <Enter>. Please note the characters may or may not be echoed by the CRT.
ESTeem
-------------------------
ADD xxx xxx = your address
SETC yyy yyy = destination address
TERMC ON
TERMT 10
SENDP 255
EDIT OFF
XSF ON
SAVE
If EDIT is off, and SENDPAC = 255, the SENDPAC character is disabled. This character when received will not cause packet
transmission and will be passed as normal data. The TERMC and TERMT commands are used to transmit the contents of the
ESTeem transmit buffer.
Software flow control in this example is enabled (factory default XSF = OFF) therefore the ESTeem will pass all characters except
the data flow control characters for Xon/Xoff.
HARDWARE MODE CONTROL
The MODECON (Mode Control) command is provided in the ESTeem to change the mode of the ESTeem modem from
COMMAND Mode to CONVERSE (or TRANSPARENT Mode) via a hardware control line. The hardware line is located on pin
19 of the RS-232C connector. If MODEC = ON, a "low or 0" on pin 19 (-3 to -15 vdc) will put the ESTeem in the COMMAND
Mode and a "high or one" on pin 19 ( +3 to +15 vdc) will put the ESTeem in the CONVERSE or TRANSPARENT Mode. The
factory default is OFF.
