Re: SMSQmulator v3 and the QLUB Adapter...
Hi Daniele! Interesting idea... It would certainly be helpful to potential QLUB users to have more ready access to the driver, rather than searching for it here and having to pull it off the Forum or else Dilwyn's site, but I think it does belong on the 'QL' side rather than part of the Emulator - i...

Re: Serial QPC to QL
Hi Just start with Martin's suggestion below - copy directly with COPY 'ser1hz' to 'con_' on the QL to avoid latency waiting for tokenisation - and get a clearer idea of precisely how many characters arrive successfully before things 'hang' (and the I might suspect your USB to Serial adapter on the ...

Re: Software updates

Re: Serial QPC to QL
Hi again Jbizzel! A few points: A. Did you use the device names 'ser1hz' or just 'ser1'? B. The 2x SER ports on the QL are indeed wired differently - RX/TX and RTS/CTS are swapped between them, so I would expect you to need a different wiring than you show in that image for SER2. (SER1 is wired and ...

Re: Serial QPC to QL
Hi again! Glad to hear that. I shall assume that you are using the handshaking option as suggested, so as to avoid buffer overrun across the Serial link. Also, that your serial cable actually has the handshaking lines correctly wired (RTS/CTS). Depending upon just how long you are waiting before hit...
