Command: &V1	Display Last Connection Statistics
Description:	Displays the last connection statistics in the following format (shown with
	typical results):
	TERMINATION REASON	LOCAL REQUEST
	LAST TX rate	26400 BPS
	HIGHEST TX rate	26400 BPS
	LAST RX rate.	49333 BPS
	HIGHEST RX rate	49333 BPS
	PROTOCOL	LAPM
	COMPRESSION	V42Bis
	Line QUALITY	038
	Rx LEVEL	015
	Highest Rx State	67
	Highest TX State	67
	EQM Sum	00B4
	Min Distance	0000
	RBS Pattern	00
	Rate Drop	00
	Digital Loss	2000
	Local Rtrn Count	00
	Remote Rtrn Count	00
	Flex 9481814347C4

RBS Pattern: Shows which bits are being robbed in the least significant 6 bytes, e.g., 03 indicates 2 robbed bits in bit positions 0 and 1.

Digital Loss: Shows if a pad was encountered and if so, what was the digital loss. 2000 means 0dB.

Flex: Shows V.8bis information as follows:

First byte: Octet 13 (second byte of manufacturer id, 94 = 56K)

Second byte: Octet 14 (Licensee code: 81 = Conexant)

Third byte: Octet 15 (manufacturer's product capabilities)

Fourth byte: Octet 16 (56K version number)

Fifth byte: Octet 17 (Conexant pump code version number)

Sixth byte: Octet 18 (x-law and controller version number)

Bit 6 Forced/Not forced A-Law/µ-Law

0= Forced A-Law/µ-Law.

1= Not forced A-Law/µ-Law.

Bit 5 Select A-Law or µ-Law

0= Select A-Law.

1= Select µ-Law.

Bit 4:0 Controller version
