Long space disconnect. Modem hangs up after 1.5 seconds or more of continuous space while
on-line.
Y0
Disable.
Y1
Enable.
Z
Hard Reset - Resets the modem. (Same as asserting RESET# on pin 24).
:E
Read from serial EEPROM.
:I
Interrupt read. This command causes the modem to report the lower 8 bits of the interrupt
register IO Control 0 (U70). The CID, OCD, PPD, and RI bits are also cleared.
:M
Write to Serial EEPROM.
:P
Program RAM write. This command is used to upload firmware supplied by CCI to the modem.
Contact CCI for more information.
User-Access Register Read. This command allows the user to read from user-access
registers. The format is "AT:Raa", where:
aa = user-access address in hexadecimal.
:R
"AT:R" command causes all the U-registers to be displayed.
User-Access Register Write. Allows the user to write to the 16-bit user-access registers. The
format is "AT:Uaa,xxxx,yyyy,zzzz" where
aa = user-access address in hexadecimal.
xxxx = data in hexadecimal to be written to location aa.
yyyy = data in hexadecimal to be written to location (aa + 1).
:U
zzzz = data in hexadecimal to be written to location (aa + 2).
