oTerminal is an universal and easy to use terminal program for ethernet communication (TCP/IP) and serial ports.

With oTerminal and a standard ethernet to serial converter, it is easy to connect serial devices with different baud rates. It is also possible to connect ethernet devices that use a low level binary protocol such as Modbus. To connect direct to a RS232 of RS485 port, a serial (usb) device adapter / converter is needed.

If you have a problem using oTerminal, please don't write a review, but send us an e-mail so we can help.

Version 1.3
Review by Beagle-Hound

Doesn't support "ordinary" (non-IP) serial ports. - This only supports terminal server type devices that map IP Network ports to serial ports. (The program appears only to connect to serial devices via IP address, and cannot connect to ordinary Mac Serial Ports). I had a USB to Serial port cable, hoping to connect in to a Cisco Router. No luck -- had to get a different program! If you ARE connecting via a terminal server type remote serial-to-IP appliance, they appear to have good debugging capabilities (HEX display, for instance).

Review by UnhappyCustomer1234509876

Buyer Beware. - Horrible product. Not intutive and could not connect to any of my Cisco SSH clients via telnet or serial USB adapter. And, they ask to e-mail for support. Haven’t found e-mail yet. Or hidden so not easy to find. Website support was too basic. Found manual and would have reconsidered purchase after reading. Worst 5$ I’ve ever spent in my 20 years of IT support.

Review by helloiammacintosh

It worked for my Serial connections. - I usually don’t write reviews and just leave it up to others to comment. I initially bought it to console my Watchguard Firebox modded with pfSense. No problems/easy setup. I just bought a Foundry Fastiron LS648. Swapped my settings and compatible cable... bam. Works. I’m familiar with Windows Putty, and it does a lot, but just get me on the job to do what I need to do. It works and works very well! 5 star recommend. I hope the keywords pick up in the iTunes search engine. I scoured the web for an Apple app such as this. People should know about this solution outside of the Apple ecosystem. It solves a huge issue rather than messing with OS X terminal, or pulling out the Windows machine.
