2 Standard V.25ter AT Commands
These AT Commands are related to ITU-T (International Telecommunication Union, Telecommunica-
tion sector) V.25ter document.
MC35 supports the registers S0-S29. You can change S0,S3,S4,S5,S6,S7,S8,S10,S18 by using the
appropriate ATSn commands. All the other registers are read-only and for internal usage only!

Parameter
Reference
V.25ter
Note
• After beginning with the character “a“ or „A“, a second character “t“ ,”T“ or “/“
has to follow. In case of using a wrong second character, it is necessary to
start again with character “a“ or “A“.
• If autobauding is active (see +IPR, pg. 37) A/ (and a/) cannot be used.
2.2 +++ Switch from data mode to command mode
Execute command
+++
Response
This command is only available during data calls. The +++ character sequence
causes the TA to cancel the data flow over the AT interface and switch to com-
mand mode. This allows you to enter AT commands while maintaining the data
connection to the remote device.
OK
To prevent the +++ escape sequence from being misinterpreted as data, it must
be preceded and followed by a pause of at least 1000 ms. The +++ characters
must be entered in quick succession, all within 1000 ms.
