Some switches have multiple serial ports.

I am running 10.5.8 on a MacBook Pro with 2.4 GHz Intel Core 2 Duo. Note: Appendix A provides an example of configuring and using a terminal emulator.

Sh-3.2# stty -f /dev/cu.PL2303-0000201A 19200Īm I invoking stty incorrectly, or is there just a bug in it? (Or is some third thing happening that I'm not considering?) Iflags: -icrnl -ixon -ixany -imaxbel -brkint But stty consistently fails, without complaint, to change the baud rate: while the Osborne used a memory-mapped screen like the Apple). When configuring the SMT, please make sure the terminal baud rate is also 9600bps. The screen program is able to set the baud rate of the device to a value provided on the command line, so I know that the baud rate is changeable. On a 9600 baud terminal, a whole line is 77 milliseconds, so its going to feel a bit. On the other hand, I'm having no luck using the stty command to change the baud rate of the USB-serial device (/dev/cu.PL2303-0000201A), which I need to do so that I can run a different program that wants to communicate with/control the TNC. Using screen, I can type at the modem's command prompt, and it sends me back reasonable answers. I know that the cable and driver work, because I'm able to connect to an external device (a TNC = packet radio modem) connected via this cable, using the screen program (a VT100 terminal emulator). I have a USB-to-serial converter cable that has the Prolific chepset, and that uses the osx-pl2303.kext driver. I'm encountering essentially the same problem, and despite scouring the various Mac OS X support forums out there, have yet to find an answer/solution/workaround. Bumping this old post that never received a response.
