Profile 1 (&F1 ) — V.110 Asynchronous Operation*
* The MTA128ST-USB is manufactured in two builds. To determine the build of your terminal adapter
(TA), issue the ATI2 command in a terminal window. If the TA responds to the command with MTA128ST-
USB, then it supports V.110. If your TA resonds to the ATI2 command with MTA128ST-USB-RC, V.110
support is not available.
