Is there any cell phones I can get that have a 9 pin d shell type rs-232 cable that look like a standard modem when they are connected to a com port. I can't install any drivers because I won't be connecting it to a computer. Instead I will be connecting it to a processor that understands DF1 Full Duplex and will allow me to configure; baud, parity, control line, CRC... the usual. Thus it needs to look like a modem when it is connected to the processor. I will be calling into it so it needs to auto answer. Calling out through it would also be nice but not a requirement.
