Specifications of HMS91C7432

Example 4. HMS91C7432 request for missing connection info

When the HMS91C7432 is going to make a connection to the internet or to a mail server, it will

check if all necessary info is available. The connection info may be erased due to memory

overlaying. Upon an internet session is ended, HMS91C7432 will clear its memory pool for

another session. Whenever connection info is needed, HMS91C7432 will issue a request to the

host for such info. The request will be made using complex command mode with control code

0x01 followed by a Data ID as listed in Table 5.

0x7E

Sync 2

0xFE

Control

0x01

Length

0x01

Data ID

0x08

This example demostrates a request made by the HMS91C7432 for the POP3 server’s domain

name when it is going to logon to the POP3 server.

Example 5. HMS91C7432 returning result code to the host

There are sets of Result Code coresponding to each command issued by the host to the

HMS91C7432. The HMS91C7432 returns at least one result code to each command, to report

the result of execution or the status of the connection. HMS91C7432 returns the result code by

using complex command mode with control code 0x02 followed by the result code (in the Data

ID field) as listed in Table 6.

Sync 1

0x7E

Sync 2

0xFE

Control

0x02

Length

0x01

Data ID

0x49

This example demonstrates a result code returned from HMS91C7432 to report that the

authentication check is passed and the system is ON LINE (Logon to the ISP is success).

Example 6. Host requesting Connection Status and the HMS91C7432 returns

User may make a request for the connection status at any time during the internet session. The

host may make its request by using Simple Command Mode with Control Code 0x04. The

HMS91C7432 will return the connection status by Complex Command Mode with Control Code

0x03 followed by the connection status code as listed in Table 7.

This example demonstrates how the host makes a connection status request and how the

HMS91C7432 responds to this request. The host made the request after a successful logon to

the POP3 server. The HMS91C7432 report that the system has logon to the POP3 server.
