The async control character map speciﬁes a value representing one or more

asynchronous modem control characters for the peer to recognize (“escape”) and

that may occur in the data packet. Each bit in the map corresponds to one control

character, 0x00 (the right end of the map) through 0x1f (the left end of the map);

that is, 0 through 31, decimal. The actual map is a value used essentially as a

mask. For example, the default map value, 0xa0000 (655360 decimal) allows the

escaping of the control characters 0x11 (XON) and 0x13 (XOFF) if they occur in

the data stream. The values 0x7d and 0x7e are always escaped.

If you have a modem that requires control characters different from the default,

you can build your own async control character map. Determine the

corresponding bit for each character by converting the hex value of the control

character to decimal. For example, 0x1f = 31 decimal; so to escape that character,

set the leftmost bit in the map. Do the same thing for each control character. Once

you’ve decided what bits in the map to set, you can enter either the hex character

equivalent to the bit string or the decimal equivalent. To escape all control

characters in the packet, set the map to 0xffffffff. For a description of how PPP

encodes escaped control characters in the data stream, refer to Chapter 2.

PPP displays the decimal number equivalent to the string and uses that value in its

link negotiations.

Using the BCC

The BCC does not allow you to conﬁgure this parameter.
