ESC= 1 byte, 0 or 1 Command or query. (IBS and ESC++ feature)
ESC=x
Where: x = 0 (Disable the high-rate ESC)
x = 1 (Enable the high-rate ESC)
IBS ESC may only be enabled when:
1. Both Tx and Rx framing modes are set to IBS.
2. Data rate is not 1544 kbps (as spare overhead
bits are not available in this mode).
3. IBS high-rate ESC FAST option is enabled.

Parameters
SCP= 2 bytes,
numeric
Command or query. (IBS and ESC++ feature)
Allows control of the ESC baud rate and character
format, where x is the index for baud rate:
0=1200 baud
1=2400 baud
2=4800 baud
3=9600 baud
4=19200 baud
5=38400 baud
6=14400 baud
7=28800 baud
and where y is the character format (data bits, parity,
stop bits):
0=8N1 char format
1=7E2 char format
2=7O2 char format
The baud rate may be limited by the data rate. The ESC
baud rate breakpoints (determined by data rate) are
shown in Chapter 6 and Chapter 13. A response of SCP*
will indicate if the data rate will not allow a selected baud
rate to operate.
