-
- CDTRAP is a program used to monitor the modem whileì
- "outside" the Fido system, and reboot the system if carrierì
- is lost.
-
- The assumption here is that you are using Fido's O)utside orì
- E)xitDOS command for sysop-only access to DOS commands.ì
- Without CDTRAP or a similar program, if you wereì
- disconnected for some reason, your computer would ì
- mindlessly wait for the next command, but since Fido is noì
- longer in control it would sit there until you manuallyì
- rebooted the machine.
-
- (Previous Fido versions would give the NEXT PERSON WHOì
- CALLED IN access to your DOS.)
-
- CDTRAP is easy to use: in your batch file (see sampleì
- "RUNFIDO.BAT" on Fido Software's BBS) you install CDTRAPì
- before you run COMMAND.COM; before you exit to Fido, you un¡
- install CDTRAP.
-
-
- CDTRAP ;installs it
-
- CDTRAP R ;removes it
-
- When CDTRAP is run, it first checks to see if was installedì
- previously; if so, it turns that previous copy "ON" or "OFF"ì
- as indicated. Only if there is no CDTRAP resident does itì
- install itself in memory.
-
- CDTRAP as supplied inserts itself into the PClones timerì
- tick, and monitors the modem status port of COM1 every tick,ì
- or 55mS. If carrier is lost it causes the system to reboot.
-
- To use CDTRAP with COM2, or a non-PClone machine, you willì
- need to edit and reassemble the program.
