&Un
With n > 0, sets the floor connect speed, lowest acceptable connection speed. &Nn is the ceiling connect speed (&N=0
&U=0 connects at highest speed available):
If your modem cannot connect to the remote modem at or above the speed set with this command, the modem will hang
up.
&Wn
Modifies user-defined NVRAM settings:
• &W0 — modifies Y0 settings.
• &W1 — modifies Y1 settings.
&Yn
Determines how a modem responds when a break signal is received:
• &Y0 — destructive, non-expedited: data being processed by modem receiving break is destroyed, break is not sent to
other modem.
• &Y1 — destructive, expedited: data being processed by both modems is destroyed, break is sent to other modem.
• &Y2 — non-destructive, expedited: data being processed in both modems is not affected, break is sent to other
modem.
• &Y3 — non-destructive, non-expedited: data being processed in both modems is not affected, break is not sent to other
modem.
&Zn=s Writes phone number s to user-defined NVRAM where n = 0 through 3.
&Zn? Displays phone number in user-defined NVRAM at position n where n = 0 through 3.
