[Prior Art] Conventionally, a so-called teletypewriter has been used as a maintenance operation terminal for electronic exchanges that uses special interrupt signals. A signal was being sent out. However, production of teletypewriters has now been completely discontinued and new products are no longer available, whereas electronic switching machines are guaranteed to last for 20 years due to their nature. However, teletypewriters have many mechanical parts and cannot be used continuously for the same period of time as electronic exchanges, so some kind of replacement is required.

[0003] Generally, a so-called TTY mode, which is built into personal computers from the beginning, can be used as a substitute for a teletypewriter. However, in some types of electronic exchanges, the interrupt signal sent when the maintenance operation terminal starts using R is not a code representing a general special symbol.
By sending a signal for a certain period of time on one specific lead on the S232C interface, it may be treated as an interrupt signal, and this type of electronic exchange cannot be used in the built-in TTY mode of personal computers from the beginning. there were. Therefore, it is not possible to directly connect a personal computer to this type of electronic exchange, and special hardware that has an interrupt key and an interrupt signal is added in the middle, or the interrupt logic on the electronic exchange side has to be changed to a code system. It required modifications such as changes.

[Problems to be Solved by the Invention] The conventional method of adding special hardware between a personal computer and this type of electronic exchange has poor operability and requires power wiring for the special hardware. Met. In addition, in the method of modifying this type of electronic switchboard and changing the interrupt signal to the code system, the electronic switchboard to be modified is still in service, and the modification is dangerous. This was almost impossible because the interface itself of the maintenance operation terminal, which instructs and operates necessary changes to the operating mode of the exchange, would have to be modified.
