		Table 104. Bit Errors (Continued)
Data			Meaning
19	B2		HDLC Flag detected
		Beginning of Packet
92 6E EF 14 65			Spurious data
19	B0		Data byte with more than 6 mark bits in a row. The
			modem looks for HDLC flags.
19	B2		HDLC Flag detected
		Beginning of Packet
DA BE C6 07 EA D8 31 C2 05 3C FA C8 86 C4			Spurious data
40	E6
19	A0		Transparency code, represents 0x11 data byte found in
			receive data.
CA EA A8 F9			Spurious data
19	B2		Calculated CRC not equal FCS. The modem assumes
			this is a bad Frame.
		Beginning of Packet
8D 00 57	A5	43 29	Spurious data
19	B0		Followed by a data byte with more than 6 mark bits in a
			row. The modem looks for HDLC flags.
19	B2		HDLC Flag detected
		Beginning of Packet
05 CB 14 9F 7C 2D			Spurious data
19	B0		Followed by a data byte with more than 6 mark bits in a
			row. The modem looks for HDLC flags.
19	B2		HDLC Flag Detected
19	B2		If there is 1-bit error received in an HDLC flag, the
			modem assumes a new single-byte packet. Since a 1-
			byte packet is invalid, 19 B2 is generated by the modem.
19	BA		Loss of Carrier Detected
0D 0A 4E 4F 20 43 41	52	52 49 45 52 0D 0A	NO CARRIER
