#136031 - TTL vs RS232 |
If one of the devices in a RS232 handshake does not have control lines (all that are available is TX/RX DTR and RTS lines - no CTS) how can I handshake to a full RS232 on a PC - does this mean I have to use software flow control? I have a line level matcher for the TTL lines to bring them up to RS232 voltages but only TX/RX lines exist on this device. Thanks for any advice. |
