1.4 External Computer Components
The following information provides new mechanical changes to the models, which are different
from earlier models
Universal Serial Bus
A Universal Serial Bus (USB) connector has been added to select models on the left side of the
computer. The connector provides an interface for USB peripheral devices.
On models without the USB connector, a plastic insert covers the connector space. The plastic
USB cover is included in spare part 254981-001, the miscellaneous spare parts kit. The kit also
ships with such items as replacement clutch covers, rubber feet, battery spacer door, etc. (See
Chapter 4 in the Maintenance and Service Guide for miscellaneous spare parts.)
Battery Spacer Door
IMPORTANT: The Battery Spacer Door, which is a component of the Dualbay compartment, has
been modified.
The new battery spacer door pushes 1pushes inward with a single motion, as compared to the
previous version 2which pulled out and pushed inward (
Figure 1-1).
NOTE: The Battery Spacer Door is included in the miscellaneous spare parts kit (spare part
254981-001).

Appendix C
Modem Commands
This section includes modem commands for the 56Kbps internal modem. The telephony modem
is designed to operate with the preinstalled software in the computer. The modem is compatible
with Microsoft Windows 95 (and later) or Windows NT 4.0.
Table C-1
Modem Commands
Command Description
A Answer Command. A instructs the modem to go off-hook and answer an incoming call.
Bn Communication Standard Setting. Bn determines CCIT vs. Bell standard.
0: Selects CCITT V .22 mode when the modem is at 1200bits/s
1: Selects Bell 212A when the modem is at 1200bits/s (default).
2: Unselects V23 reverse channel (same as B3).
3: Unselects V23 reverse channel (same as B2).
15: Selects V.21 when the modem is at 300 bits/s
16: Selects Bell 103J when the modem isat 300 bits/s (default).
Result Codes:
OK n=0, 1, 15, 16
ERROR Otherwise
Cn Carrier Control. The modem will accept the C1 command without error in order to assure
backward compatibility with communications software that issues the C1 command.
However, this modem does not support the C0 command. The C0 command may instruct
some earlier modems (such as the Smartmodem 1200) to not send carrier (ie., it puts them
in a receive-only mode).
0: Transmit carrier always off.
1: Normal transmit carrier switching.
Result Codes:
OK n=1
ERROR Otherwise Continued
