do what we do for dialing other computer through a serial external modem An external modem has already been suggested, and he's said it's no good: http://www.8052.com/forum/read.phtml?id=105717 using this com/rs232 port now same things can be applied with 8051 and IC max232 using its RS232/serial port of 8051 A module will (almost certainly) use a logic-level interface - so an RS232 transceiver must not be used! Just a straight logic-level connection direct to the processor pins. Check the module datasheet! However, the AT commands, etc, for the module will (almost certainly) be exactly the same as for an external modem. also some derivaties of 8051 have full duplex serial port As far as I know, all 8051s have a full-duplex serial port? |
