Hello all,
I use Proterm 3.1 with my Apple IIc and WiModem232 V2 @ 9600. I use the suggested initialization string and driver:
Generic Fixed Speed (RTS/CTS) driver
Init string: ATX1&C0&K1&S1
Apple //c Serial Port
The cable is this:
1 Handshake Out 20 DTR
2 Data Out 2 TxD
3 Ground 7 Gnd
4 Data In 3 RxD
5 Handshake In 6 DSR
Proterm 3.1 can initialize the modem upon startup successfully.
When I use Proterm's Dial function, Proterm does not recognize that the modem connected. I work around that by going on-line (solid-apple T) and dialing out using ATDS=X, where X is the index of the saved url. Interestingly enough, Proterm 3.1 does dial out if I use the Smartmodem 300 driver.
ZModem downloads start giving errors after the first time the computer saves the file to disk; Proterm reports that it was expecting one type of packet but got another (don't recall the exact packet types now). I need to cancel the download manually and power cycle the modem.
When I don't do a file transfer and use +++ to get the modem's attention, and then ATH to disconnect, I do not receive anything else from the modem. I can see the modem disconnected (through the OLED display), but I get no response from AT commands (although I also do see the modem gets the commands once again through the OLED display).
Any ideas of what could be wrong?
Thanks
Armando
