@Z Escape to OS

To return to Softmodem application from the linux prompt, type “tsc_1922_CRLF” from the
root directory.
+++ Escape Sequence
During a data connection, the escape command (+++) returns you to Command state
without terminating the data connection so you can enter AT commands. The TSC
Softmodem supports the TIES (Timing Independent Escape Sequence) escape, not the
patented Hayes escape. The +++ must be followed by a valid AT command for the escape
to be recognized. If a non-AT command follows the +++, the modem will return to the data
mode. Giving the TSC Softmodem a “+++AT” is also valid for escaping to the on-line
command state.
