S30 DTE CTS

Determines the delay required immediately before and after entering the escape com- mand for the Express XRT to recognize and execute the command.

Range = 0 to 127

Miscellaneous bits (bit 8 is most significant bit).

Bit 2 = 1:Enables on screen echo of AT com- mands.

Bit 2 = 0:Disables on screen echo of AT com- mands.

Bit 3 = 0:Enables AT responses from theEx- press XRT.

Bit 3 = 1:Disables AT responses from the Ex- press XRT.

Bit 4 = 1:Enables AT responses to be dis- played in text form.

Bit 4 = 0:Enables AT responses to be dis- played in numeric form.

Bit 5 = 0:Do not toggle Bit 5 = 1:Toggle

E Bit 80 <-> BF when using V110

Bit 7 = 1:Disable PPP ACCM spoofing. Bit 7 = 0Enable PPP ACCM spoofing. Bit 8 = 1:Ring indicator uses cadence. Bit 8 = 0:Ring indicator remains on.

Asynchronous BONDING method. 0 = ADTRAN revision 0 (default)

1 = Multi-vender option

Miscellaneous message bits (bit 8 is most

significant bit).
Bit 5= Bit 6 = Bit 7 = 1	Allows connect mes-
sage with baud rate.
Bit 5= Bit 6 = Bit 7 = 0	Connect message
without baud rate.

Determines time, in hundredths of a second, that must elapse before the Express XRT rec- ognizes a change in DTR.

Range = 0 to 255

Value determines whether or not PPP will be a single-link or multilink connection. 0=Single-link operation (default) 1=Multilink operation

2=Use compression

Controls the operation of the DTE connector CTS line.

0=Follows RTS 1=Force CTS
