U.S. Robotics I-modem Command Reference
Appendix A: Alphabetic Command Summary • Page A-23
&Y3 Nondestructive, unexpedited; the I-modem sends a break-in-sequence with
data received from your computer or terminal.
Note If the call is under MNP5 data compression, destructive breaks cause both
modems to reset their data compression tables. When transmission
resumes, the modems build new tables, and the result is lower-than- normal
throughput.
&Zn=sStore up to 10 numbers in NVRAM, where n is the position 0*9 in NVRAM, and
s is the phone number string. The number string may be up to 36 characters long,
including any Dial command options.
AT &Z2=555-6789 <Enter>
Note Do not include modem settings in the &Zn string. If the call requires a spe-
cial setting, insert it in the command string before the DSn command.
In the following example, &M0 (no error control) is inserted before the Dial com-
mand:
AT&M0 DS2 <Enter>
Note The &Zn=s command functions differently when Dial Security is enabled.
