Optimal Channel Usage; Host Side Mux Driver Designs - Wavecom GX64 GSM 27.010 Multiplexer Feature Application Note

Optimal Channel Usage

A host application can choose to use more than two channels. For example, one for
AT commands such as SMS commands and +CSQ command, one for unsolicited
responses, and one or more for on board TCP/IP socket connections, where each
socket connection runs in a separate channel.
It is generally good idea that a host application uses as few numbers of channels as
possible, thereby minimizing the use of resources (memory, processing power, etc.)
on both the host application side and GR/GS64 side. Although user data channels
have same priorities, as explained in section 6.6, a heavily utilized channel could
delay the servicing of other channels. The number of channels should be carefully
considered up front for the host application design.

Host Side MUX Driver Designs

In a typical host application that uses MUX, 27.010 is part of a port driver which
includes a port emulation entity that supports serial communication APIs. The
communication APIs vary from operating system to operating system and from device
to device.
Response, and Confirmation that can be used by all port drivers. The services are
shown in the Figure 3.
