SSC, IIe, 9600 Test?

[admin]

Let's look at what the string does:

ATE0V1Q0S0=0S7=99S8=2&C0&D0

E0 = turns off the echo (means nothing you type in command mode is going to show)
V1 = turns on verbose mode (this is already set to 1 by default with the WiModem232)
Q0 = this turns on result codes (this is already set to 0 by default with the WiModem232)
S0 = turns off auto-answer (this is already set to 1 by default with the WiModem232)
S7 = wait for carrier after dialing (not used because we don't have a phone line)
S8 = duration for delay for comma (not used because delays are not necessary)
&C0 = set DCD to always on (the default is 1 for the WiModem232, which follows the actual connection state)
&D0 = Use normal DTR (this is already set to 0 by default with the WiModem232)

I recommend using an init string of ATX1&C1&K1 with ProTERM's modem drivers, and using the Generic 2400 baud or Generic Fixed-Speed (RTS/CTS) for 9600 baud.

You could try an init string of just ATX1&K1 (without the &C1).  It could be that the SSC needs to always think it is connected.
