The London Perl and Raku Workshop takes place on 26th Oct 2024. If your company depends on Perl, please consider sponsoring and/or attending.

Changes for version 1.02

  • Made sure the transaction counter, which can hold no more than two digits, will never go beyond 99.
  • Introduced a timeout while waiting for a ACK/NACK response from the SMSC. Note, that the timeout depends on the alarm() function, which unfortunately is not implemented on all systems.
  • Made sure that when methods are called in void context, they will return undef.
