Ok so after resetting the wimodem to factory settings I find i'm still having the same problem where at 2400 baud i'm able to connect to the wimodem itself but the apple II freezes. I also find that at 300 and 9600 baud I can connect to the wimodem but the apple ii doesn't even aknowledge the connection and continues waiting for a call. here's my settings in proterm (after setting the init string to ATX1&C0&S1):
B0 C0 E1 L0 M0 N0 Q0 V1 X1
S0:1 S1:0 S2:43 S3:13 S4:10 S5:8 S6:2 S7:99 S8:2 S9:6 S10:15 S11:90 S12:50 S25:0 S30:0 S37:6 S73:0
*B2400 *BL4096 *BT5 *C0 *CT1 *D1 *HO25 *L6400 *LED4 *P1541 *R0 *T0
&C0 &D0 &G0 &K0 &Q0 &S1
on gbbs i'm using the init string ATS0=1X1&C0&S0 except for 9600 baud in which I used ATSO=1X1&C0&K0&S0
