ProTerm is picky about the driver. There is a driver for the Apple IIc because that cable is different.
Setting &C0 tells the terminal program that the modem is ALWAYS connected (online). This really should be &C1 so that connection state follows the actual connection state (connected to a BBS or not).
For the Apple IIc with your cable you want to use &K0 to disable flow control. DTR/DSR is not a supported mode. If you changes the cable to be normal (using RTS/CTS) then you can use &K1.
&S0 does nothing... it is ignored.
As far as Zmodem protocol is concerned... this is difficult to make work because there are many factors involved due to this being a wireless (WiFi) connection instead of a hard-wired (telephone) line. Zmodem has a critical ACK window that must be met. The speed of your router and ISP all play a part in how fast the ping times are. Too slow and you will get errors. Another reason for errors is using the wrong protocol for the BBS you are calling. If you are calling a "Telnet" based BBS then you need to enable Telnet translation or file transfers (any protocol) will not work.
