This S-register stores the ASCII value of the escape sequence
character.
Value may be 000 through 127 (see comments); factory-default setting
is 043, the ASCII code for a plus sign (+).
no
Setting the value greater than 127 will disable escape sequence
detection, in which case the escape sequence cannot be used to move
to command mode. The operation of the Data Terminal Ready (DTR)
circuit, set by the &D command, can still be used to move to command
state without disconnecting the call.
