PAR_ABORT port_number(SMSQ/E only)

Location ST/QL, SMSQ/E

This command clears out all of the closed PAR buffers and then sends an ‘aborted’ message, to the PAR device, thus effectively stopping the computer from sending any information still in the buffers through the PAR device. Any open channels connected to the port are unaffected.


Although the SMSQ/E implementation allows a port to be specified, there are currently no implementations of the QL which have more than one parallel port, therefore trying to pass a port_number at present results in a bad parameter error.


SER_ABORT and PRT_ABORT are very similar. PAR_CLEAR clears out the buffers but does not tell anyone. PRT_ABT is similar on the Trump Card and Gold Cards.
