These two days need to develop a program to implement the GSM at command into CDMA at the command set (in order to tie in with another GSM at command of the third party SMS program access to our CDMA Modem), considered, decided to use the virtual serial port of the way to achieve, Is that we develop a gateway program control modem, while in the system simulation of a new serial

VMware Workstation provides two ways to access virtual machines, one bridge, one Nat,bridge to get a public address, and NAT to be an intranet address.NAT is equivalent to using a host as a NAT translator, and we can add port mappings so that the extranet can access virtual machines that use NAT to surf the web.Here are two examples ofThe host environment used is

Currently, both the on-board and PND devices have the function of automatically correcting the system time. The implementation method is generally when GPS is used (of course, for devices with CMMB module, you can also use CMMB for calibration ). However, because the serial port device is an exclusive device, the GPS serial port cannot be used by the navigation software and calibration program at the same t

In the Ubuntu virtual machine, the Meteor daemon runs, requires a terminal connection, and requires a port map of the Ubuntu virtual machine and Windows (the virtual machine shares the IP address with the host). The following steps are set: 1. Click Compile, Virtual networ
