Thus, the mask for XON/XOFF (DC1 and DC3) equals the OR function
of 0x00020000 and 0x00080000, or 0x000a0000.
When the RA 6300 sends an ACCM to the host, it follows this calculation
to determine the initial value requested:
• The value set for ppp_acm (a 32-bit integer) is read in as
the ACCM.
• If input_flow_control is set to start/stop, the following two
additions are made:
If input_start_char is 0–31 decimal, the bit indexed by this
parameter is set in the ACCM.
If input_stop_char is 0–31 decimal, the bit indexed by this
parameter is set in the ACCM.
• If output_flow_control is set to start/stop, the following two
additions are made:
If output_start_char is 0–31 decimal, the bit indexed by this
parameter is set in the ACCM.
If output_stop_char is 0–31 decimal, the bit indexed by this
parameter is set in the ACCM.
For example, the initial ACCM sent to the peer is 0x000A0001 if
ppp_acm is set to 0x00000001 (i.e., the ASCII NUL character will not
be sent) and the following parameters are set as indicated:
input_flow_control
input_start_char
input_stop_char
output_flow_control

output_stop_char
