Turn-on and reset behavior

When the XMP 2600 is powered-up and the time out feature was enabled when the XMP

2600 was last used, one of two things may happen, as summarized below:

Power On Retain	Time Out counter starts
enabled	immediately following the retain operation
disabled	following the first character received from the remote controller

If the XMP 2600 is being reset using the front panel key combination (DEL+LCL) then the time out feature will be disabled. All other reset operations do not disable the time out feature.

Time out events as reflected in the status structure

Bit 3 of the Status Byte Register (read with *STB or Serial-Poll) is assigned to the Remote Communications Time-Out Event. The bit will be set when such an event occurs and if the corresponding bit of the Service Request Enable Register is set then the event will cause an SRQ to be generated.

The status bit is cleared when the TORST command is issued.
